Calculations:

 

Formula Weight (Molar Mass) of Anhydrous Copper (II) Sulfate:

 

 FWanhydrous copper(II) sulfate (g/mol): 159.62 g/mol

 

 FWwater  (g/mol): 18.016 g/mol

 

Moles of Anhydrous Salt:

 

1.112 g CuSO4 x  1 mol CuSO4 = 0.006970 mol CuSO4

     1                   159.62 g CuSO4

 

Moles of Water Lost After Heating:

 

0.634 g H2O x  1 mol H2O= 0.0352 mol H2O

     1               18.016 g H2O

 

Molar Ratio Between CuSO4 and H2O :

 

CuSO4 : 0.006970 = 1

             0.006970

 

 H2O : 0.0352     = 5

          0.006970

 

Molar Ratio: 1:5
