How many moles sulfuric acid are in 15.0 mL 6 M H₂SO4? Show work!
Mole sulfuric acid =???
Please help
Answer:
0.090 moles
Explanation:
The number of moles of sulfuric acid in 15.0 mL of 6 M H₂SO₄ can be calculated using the formula:
moles = concentration x volume
where concentration is in moles/liter and volume is in liters.
Since the volume of sulfuric acid is given in milliliters (15.0 mL), we first need to convert it to liters:
15.0 mL = 15.0 x 10^-3 L
Now, we can calculate the number of moles of sulfuric acid:
moles = 6 M x (15.0 x 10^-3 L) = 0.090 moles
So, 0.090 moles of sulfuric acid (6 M) are in 15.0 mL of 6 M H₂SO₄.
what is the molarity of a 11.0 % by mass glucose (c6h12o6) solution? (the density of the solution is 1.03 g/ml .)
11.0 grams of glucose in 100 grams of solution.
Grams of H2O = 100 – 11.0 = 89 H2O
11.0 grams glucose x 1 mole glucose/ 180 grams = 0.0611 moles glucose
1.03 grams solution/ 1 mL solution x 1000 mL liter = 1030 grams solution/liter
[11.0 grams glucose/100 grams solution] x 1030 grams/liter =113.3 grams glucose/1 liter
113.3 grams glucose/1 liter x 1 mole glucose/180 g = 0.629 M
Molarity = 0.629
molality = moles of glucose/kilogram H2O
0.0611 moles/ 89 g H2O x 1000 g/1kilogram = 0.686 molality
A solution of glucose (C6H12O6) that is 11.0% by mass has a molarity of 11.0 grams of glucose per 100 grams of solution has 0.686 molality.

a rigid plastic container holds 40.29 g of propane gas (c3h8) at a pressure of 860.6 torr. what is the pressure (in torr) if 6.41 g of propane is removed at constant temperature? enter to 1 decimal place.
The pressure of a rigid plastic container after removing 6.41 g of propane at constant temperature is 554.4 torr.
The pressure of a gas in a container depends on its volume and number of moles of gas, as described by the ideal gas law:
PV = nRT
where P is pressure, V is volume, n is the number of moles of gas, R is the gas constant, and T is temperature (assumed constant).
So, if 6.41 g of propane is removed from the container, the number of moles of gas will decrease, and the pressure will decrease as well.
To calculate the new pressure, we need to calculate the number of moles of propane in the container both before and after the removal, and then use the ideal gas law to find the new pressure.
First, we calculate the number of moles of propane before the removal:
n = m/M
where m is the mass of propane (40.29g) and M is its molar mass (312.01 + 81.01 = 44.09 g/mol).
n = 40.29 g / 44.09 g/mol = 0.9107 mol
Next, we calculate the number of moles of propane after the removal:
n = 6.41 g / 44.09 g/mol = 0.1455 mol
Finally, we use the ideal gas law to find the new pressure:
P1V1 = n1RT
P2V2 = n2RT
V1/V2 = n1/n2
P2 = P1 (n1/n2)
P2 = 860.6 torr × (0.9107 mol / 0.1455 mol)
P2 = 554.4 torr
The pressure after 6.41 g of propane is removed will be 554.4 torr.

imagine, you are boiling an egg. what would be the best method for raising the boiling point of water in a kettle by a few degrees celsius to have it done sooner?
Adding a solute to water can be an effective way to raise its boiling point and speed up the boiling process.
What is the method of raising boiling point?
To raise the boiling point of water in a kettle by a few degrees Celsius and have the boiling process done sooner, you could add a solute that can increase the boiling point of water. Some common solutes used for this purpose are salt (sodium chloride), sugar, and baking soda (sodium bicarbonate).
When a solute is added to water, it disrupts the hydrogen bonding between water molecules and requires more heat to convert the solution into steam. This increase in the energy required to boil the solution results in a higher boiling point.
For example, adding salt to water can increase its boiling point by about 1°C for each 58 g of salt per liter of water. However, it is important to note that adding too much solute can also reduce the solubility of the solute, and the solute may precipitate out of solution if the concentration becomes too high.

will the amount of shielding increase, decrease, or stay the same as more valence electrons are added to the same energy level?
The amount of shielding will generally increase as more valence electrons are added to the same energy level.
Shielding Effect
In atomic physics, shielding refers to the process by which inner electrons shield or screen the positively charged nucleus from the outer electrons. The more electrons there are in an energy level, the greater the shielding effect. As more valence electrons are added to the same energy level, the effective nuclear charge experienced by the outer electrons decreases, resulting in increased shielding. This increased shielding means that the electrons will experience a weaker attractive force from the nucleus, making it less difficult for them to be removed from the atom or molecule, and therefore increasing the stability of the electron configuration.

In 1863 John Newlands presented a paper, classifying the 56 discovered elements into 11 groups based on similar physical properties. He noted that pairs of similar elements existed which differed by some multiple of eight in atomic weight. In 1864 Newlands published his version of the periodic table and proposed the Law of Octaves, stating that any given element exhibits analogous behavior to the eighth element following it in the table. Dimitri Mendeleev noticed patterns in the properties and atomic weights of halogens, alkali metals and alkaline metals. He also observed similarities between the series CI-K-Ca, Br-Rb-Sr and I-Cs-Ba. In an effort to extend this pattern to other elements, Mendeleev created a card for each element, containing the element's symbol, atomic weight, and chemical and physical properties. As Mendeleev arranged the cards in order of ascending atomic weight, grouping elements of similar properties together, the periodic table was formed. Although Mendeleev's table demonstrated the periodic nature of elements, during the next century, scientists accurately explained why the properties of the elements recur periodically.
Rutherford discovered nuclear charge and this charge, later termed the atomic number, was used to number the elements within the periodic table. Finally variations of the same elements, or isotopes having the same number of protons and electrons but differing numbers of neutrons, were discovered. How did later discoveries change the model of Mendeleev's periodic table to what we accept today?

how mayn grams of sodium acetate mustbe added to 1.00 l of a .200 m acetic acid solutioj to form a buffer of 4.20
18.04g of sodium acetate must be added to 1.00L of a .200M acetic acid solution to form a buffer of 4.20.
The formula for sodium acetate (NaC2H3O2) is Na+ + C2H3O2-.
To calculate the amount of sodium acetate needed to form a buffer of 4.2, we need to use the Henderson-Hasselbalch equation:
pH = pKa + log([base]/[acid]) where [base] is the concentration of the base (sodium acetate) and [acid] is the concentration of the acid (acetic acid).
Given that the acetic acid concentration is 0.200 M,
we can solve for the concentration of sodium acetate needed to achieve a pH of 4.2 when pKa of acetic acid = 4.75 then:
4.2 = 4.75 + log([base]/0.200)
log([base]) = -0.55
[base] = 0.22 M
Now, we can calculate the amount of sodium acetate needed to achieve this concentration in 1.00 L of solution:
0.22 mol/L × 1.00 L = 0.22 mol
Then, we can convert this amount of moles to grams using the molar mass of sodium acetate.

the trigylceride (c57h110o6) content of a blood sample is 125 mg in 10.0 ml. what is the molarity of the trigylceride?
0.19 mM is the molarity of the triglyceride , the trigylceride (c57h110o6) content of a blood sample is 125 mg in 10.0 ml
The molarity of the triglyceride in the blood sample is 0.19 mM.
To find the molarity, the mass of the triglyceride (125 mg) must be converted to moles.
Then divided by the volume of the blood sample (10.0 mL).
The conversion factor is obtained by dividing the molar mass of the triglyceride (862 g/mol) by 1000 to convert to milligrams:
125 mg / (862 g/mol / 1000) = 0.145 x 10^-3 mol
The molarity is then calculated as:
0.145 x 10^-3 mol / 10.0 mL = 0.19 mM
The trigylceride (c57h110o6) content of a blood sample is 125 mg in 10.0 ml, 0.19 mM is the molarity of the triglyceride ,
