Answer:

Relative molecular mass of copper (II) sulphate crystals is 159.611 g/mol

Step-by-step explanation:

The chemical formula of copper (II) sulphate crystals is CuSO4

Molar Mass of Cu or copper - 63.546 g/mol.

Molar Mass of S or sulfur - 32.065 g/mol.

Molar Mass of O or oxygen - 16 g/mol. Hence, Mass of four oxygen molecule would be equal to 64 g/mol.

Total mass of copper (II) sulphate is
63.546+64+32.065 = 159.611 g/mol
