Dear student

The atomic mass of H is 1 g
The atomic mass of O is 16 g
The atomic mass of Cu is 63.5 g
The atomic mass of S is 32 g

The molecular mass of CuSO4. 5 H2O = Atomic mass of Cu + Atom mass of S + (4 × Atomic mass of O) + [5 × {2 × Atomic mass of H + Atomic mass of O}]

Molecular mass of CuSO4. 5 H2O = 63.5 + 32 + (4 × 16) + 5 (2 + 16) g

Molecular mass of CuSO4. 5 H2O = 63.5 + 32 + 64 + 90 g

Molecular mass of CuSO4. 5 H2O = 249.5 g
