Chloral Hydrate

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)

    Thank you for your help. I did want to clarify why you are only calculating the Molar Mass for H2 and not the molar mass for H2O (or even H2O2). I'm not sure why you did this. Please clarify. See below: The following reaction
