Hey there!:
Molar mass CuSO4*5H2O = 249.68 g/mol
Therefore:
1 mole CuSO4*5H2O ---------------- 249.68 g
3.2 moles --------------------------------- ?? ( mass of CuSO4*5H2O )
mass CuSO4*5H2O = 249.68 * 3.2
mass CuSO4*5H2O = 798.97 g
Hope that helps!

Calcium chloride dehydrate (CaCl₂ · 2 H₂O) have a molar mass equal to 147 g/mol.
Explanation:
To calculate the molar mass of calcium chloride dehydrate (CaCl₂ · 2 H₂O) we use the following formula:
molar mass of CaCl₂ · 2 H₂O = atomic weight of Ca × 1 + atomic weight of Cl × 2 + atomic weight of H × 4 + atomic weight of O × 2
molar mass of CaCl₂ · 2 H₂O = 40 × 1 + 35.5 × 2 + 1 × 4 + 16 × 2
molar mass of CaCl₂ · 2 H₂O = 147 g/mol
