How many grams of water would there be in 100.0 g hydrate? 
 52.6 grams of water would be in 100 grams of sample 
how many moles 
 52.6 grams of water @ molar mass of 18.01 g/mol H2O = 2.92 moles of H2O 

I forgot how I got these but I remember my answers..

How did you find the grams of water though?

aaronq · Answer

Mass of the hydrate 0.946g
Mass of the anhydrous CuSO4 0.614gCuSO4

mass of water = mass of hydrate - mass of anhydrous compound

$moles=\dfrac{mass~(in~g)}{Molar~mass}$

aaronq · Answer

find mass first, then moles
