how many moles are in 4.5 x 1022 molecules/atoms of co2?

Answers

Answer 1

There are 0.075 moles of CO2 are present in 4.5 x 1022 molecules/atoms of co2

Mole — what is it?

Mole is stated as the quantity of a material that consists 6.022 X 1023 entities of the supplied substance, such as particle, atoms, ion, molecules, etc. The quantity of atom, ions, or molecules is measured in moles.

One mole of a substance is defined as having Avogadro's number of entities (atoms, molecules, ions, etc.). Avogadro's number is defined as 6.022 x 10^23 entities per mole.

So, to convert from the number of entities to the number of moles, divide the number of entities by Avogadro's number:

4.5 x 10^22 entities / 6.022 x 10^23 entities/mol = 0.075 moles

Therefore, 4.5 x 10^22 CO2 molecules/atoms is equivalent to 0.075 moles of CO2.

a 14.71 g sample of nabr contains 22.34% na by mass. how many grams of sodium does a 6.45 g sample of sodium bromide contain?

Answers

1.44 grams of sodium does a 6.45 g sample of sodium bromide contain.

What is sodium bromide?

The chemical compound sodium bromide has the formula NaBr. It is synthetic. It resembles sodium chloride and is a highly volatile, white, crystalline substance. The bromide radical is frequently utilised with this salt. In the chemistry and pharmaceutical industries, this salt has several uses. It cannot naturally occur in the rocks or naturally occurring minerals due to its solubility. Halides, chlorides, and iodides are a few of the chemical substances that are recovered from the ocean water.

22.34% of the mass of Na will be present in any sample of NaBr.

Thus, the 14.71 g is unimportant.

22.34 % of 6.45 = 0.2234 x 6.45 = 1.44093g

compound a has a boiling point of 200 oc, while compound b has a boiling point of 100 oc. which is more of a safety concern?

Answers

Compound B should raise more safety concerns than compound A because the vapour pressure of the bottle of the liquid with a low boiling point will be higher than that of the liquid with a high boiling point.

What causes a compound's vapour pressure to rise? Higher intermolecular forces?

The average energy of the particles present increases as the temperature rises. That implies that a greater number of them are probably energetic enough to break off from the liquid's surface. The vapour pressure will likely rise as a result.

What causes a compound's vapour pressure to be higher?

Types of Molecules: A solid's or liquid's vapour pressure is determined by the kinds of molecules that make up the substance. The vapour pressure will be relatively low if the intermolecular interactions between molecules are quite strong. The vapour pressure will be high since the substance is relatively weak.

which intermolecular force do you think is primarily responsible for the difference in boiling point between 1-hexanol and nonanal (structures below)?

Answers

The main intermolecular force responsible for the difference in boiling point between 1-hexanol and nonanal (structures below) is induced dipole-induced dipole (London dispersion) forces.

These forces are weak, but their cumulative effect is enough to cause a difference in boiling point between these two molecules. 1-hexanol has a higher boiling point than nonanal because of its larger molecular size, which leads to stronger induced dipole-induced dipole forces.

Intermolecular forces are the attractive and repulsive forces that exist between molecules. These forces are electrostatic in nature, and include van der Waals forces, hydrogen bonds, dipole-dipole forces, and London dispersion forces.

how many grams of perchloric acid, are contained in of aqueous perchloric acid? how many grams of water are in the same solution?

Answers

The total mass of the solution: 37.6 g - 26.529 g = 11.071 g. To determine the amount of perchloric acid in 37.6 g of 70.5 wt% aqueous perchloric acid, we can first calculate the mass of perchloric acid in the solution: 37.6 g * 0.705 = 26.529 g.

Then, to find the number of moles of perchloric acid in the solution, we can divide this mass by the molar mass of perchloric acid, which is 100.5 g/mol: 26.529 g / 100.5 g/mol = 0.2645 moles. The number of grams of water in the solution can be calculated by subtracting the mass of perchloric acid from the total mass of the solution: 37.6 g - 26.529 g = 11.071 g.

you are given an irregularly shaped lump of a material and determine that it has a mass of 16.9245 g. when placed in a graduated cylinder that initially contains exactly 20.00 ml of water, the water level rises to 29.73 ml. what is the density of the unknown material? (show all your calculations.)

Answers

The density of the unknown material is approximately 1.74 g/cc

To find the density of the unknown material, we need to first calculate its volume. We can do this by finding the volume of the water that was displaced by the lump. The volume of the displaced water is given by the difference in volume of water in the cylinder before and after adding the lump.

The volume of the displaced water is equal to the final volume of water in the cylinder minus the initial volume of water in the cylinder:

V = 29.73 ml - 20.00 ml

=> 9.73 ml

Next, we'll convert the volume from milliliters to cubic centimeters (cc) since the density of the unknown material is usually expressed in g/cc:

V = 9.73 ml x (1 cc/1 ml)

=> 9.73 cc

Finally, we can calculate the density of the unknown material by dividing its mass by its volume:

density = mass / volume

density = 16.9245 g / 9.73 cc

density = 1.74 g/cc

So the density of the unknown material is approximately 1.74 g/cc.

Helium to lift the real house costs: $4,745,000The empty balloons for the model would cost $10,682.75. The empty balloon for the real house would cost. $1,423,468.75

What is a unit rate?

A unit rate is the rate at which one item of a product or service is valued.

1) The model's weight that will be used to calculate the weight of the real house is required

Whereby the model weight is 3,333 lbs, we get

Model weight = 3,333 lbs

The number of models that are equivalent to the real house = 123 model units

Weight of the real house = 123 × 3,333 lbs = 409,959 lbs

2) The weight a regular balloon can lift = 0.036 lbs

The number of balloons that would lift the model is therefore;

3,333 lbs ÷ 0.036 lbs/balloon ≈ 85,462 balloons

The number of balloons that would lift the house is therefore;

409,959 lbs ÷ 0.036 lbs/balloon = 11,387,750 balloons

3) The volume of helium in one balloon = 0.52 cubic feet

The volume of helium that would be needed to lift the model is therefore;

85,462 balloons × 0.52 cu. ft./balloon = 44440.24 cu. ft.

The volume of helium that would be needed to lift the real house can be found as follows;

11,387,750 balloons × 0.52 cu. ft./balloon = 5921630 cu. ft.

4) The formula for the radius of the sphere is; R = ∛(0.75·V/π), where;

V = The volume of the balloon or the gas it contains

Therefore, for the model, we get;

V = 44440.24 cu. ft., therefore;

R = ∛(0.75 × 44440.24/π) ≈ 21.97 feet

The radius for the balloon for the model: 21.97 feet

The diameter = 2 × 21.97 ≈ 43.95

The diameter for the balloon for the model is about 43.95 feet

The values for the balloon for the real house are;

R = ∛(0.75 × 5921630/π) ≈ 112.23

The radius of the balloon for the real house: 112.23 feet

Diameter ≈ 2 × 112.23 = 224.46

The diameter for the balloon for the real house is about 224.46 feet

5) The number of balloons that an helium tank can fill = 600 balloons

The number of tanks of helium needed to fill the balloons that will lift the model are therefore;

85,462 balloons/(600 balloons/tank) ≈ 143 tanks

(The above value is obtained by rounding up)

The tanks needed to lift the model = 143 tanks of helium

The number of tanks needed for the real house is found as follows;

11,387,750 balloons/(600 balloons/tank) ≈ 18979.53 tanks

6) The cost of the renting the extra large tank of helium to lift the model and the real house can be found as follows;

The unit rate for the cost of renting one tank = $250

The cost of helium to lift the model is therefore;

143 tanks × $250/tank = $35,750

The cost to lift the real house can be found as follows;

18979.53 tanks ≈ 18980 tanks

Cost ≈ 18980 tanks × $250/tank = $4,745,000

The cost to lift the real house is about $4,745,000

7) The cost per balloon = $0.125

Cost of the empty balloons to lift the model is therefore;

Cost of balloons ≈ $0.125/balloon × 85,462 balloons = $10,682.75

The cost of balloons to lift the model is about $10,682.75

Cost of the empty balloons to lift the real house is therefore;

Cost ≈ $0.125/balloon × 11,387,750 balloons ≈ $1,423,468.75
