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

Question

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)

Answer 1

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.
