# What is the molar mass of chloral hydrate and how many moles of C2H3Cl3O2 molecules are in 500 g chloral hydrate.

Also, what is the mass in grams of 2.0 x 10^-2 mol chloral hydrate?

Molar mass? You can add them up. Starting at the left, 2 carbons, three H, three Cl, two O. The atomic masses you are adding are in the periodic table.

Number moles= 500/molmass

Massingrams= molmass*(2.0*10^-2)

## The molar mass of chloral hydrate is 165.4 g/mol. There are 3.02 moles of C2H3Cl3O2 molecules in 500 g chloral hydrate. The mass in grams of 2.0 x 10^-2 mol chloral hydrate is 3.31 g.

## To calculate the molar mass of chloral hydrate (C2H3Cl3O2), we add up the atomic masses of each element in the compound. The atomic masses can be found on the periodic table.

The atomic mass of Carbon (C) is approximately 12.01 g/mol.

The atomic mass of Hydrogen (H) is approximately 1.01 g/mol.

The atomic mass of Chlorine (Cl) is approximately 35.45 g/mol.

The atomic mass of Oxygen (O) is approximately 16.00 g/mol.

So, for chloral hydrate (C2H3Cl3O2):

Molar mass = (2 * atomic mass of C) + (3 * atomic mass of H) + (3 * atomic mass of Cl) + (2 * atomic mass of O)

= (2 * 12.01 g/mol) + (3 * 1.01 g/mol) + (3 * 35.45 g/mol) + (2 * 16.00 g/mol)

= 119.38 g/mol

Therefore, the molar mass of chloral hydrate is approximately 119.38 g/mol.

To find the number of moles in 500 g of chloral hydrate, we can use the formula:

Number of moles = Mass / Molar mass

= 500 g / 119.38 g/mol

= 4.19 moles (rounded to two decimal places)

So, there are approximately 4.19 moles of C2H3Cl3O2 molecules in 500 g of chloral hydrate.

Next, to calculate the mass in grams of 2.0 x 10^-2 mol of chloral hydrate, we can use the formula:

Mass in grams = Number of moles * Molar mass

= (2.0 x 10^-2 mol) * (119.38 g/mol)

= 2.39 grams

Therefore, the mass in grams of 2.0 x 10^-2 mol of chloral hydrate is approximately 2.39 grams.

## The molar mass of chloral hydrate (C2H3Cl3O2) can be found by adding up the atomic masses of each element. Here's how you can calculate it:

- Carbon (C) has an atomic mass of 12.01 g/mol.

- Hydrogen (H) has an atomic mass of 1.01 g/mol.

- Chlorine (Cl) has an atomic mass of 35.45 g/mol.

- Oxygen (O) has an atomic mass of 16.00 g/mol.

To find the molar mass, multiply the number of atoms of each element by their atomic mass and then sum them up:

Molar mass of C2H3Cl3O2 = (2 * 12.01 g/mol) + (3 * 1.01 g/mol) + (3 * 35.45 g/mol) + (2 * 16.00 g/mol)

Now you can calculate the molar mass.

Next, you can determine the number of moles of C2H3Cl3O2 molecules in 500 g of chloral hydrate. The formula to calculate the number of moles is:

Number of moles = Mass in grams / Molar mass

Substituting the given values:

Number of moles = 500 g / Molar mass

Finally, to find the mass in grams of 2.0 x 10^-2 mol of chloral hydrate, you can use the following equation:

Mass in grams = Number of moles * Molar mass

Substituting the given values:

Mass in grams = (2.0 x 10^-2 mol) * Molar mass
