Find relative molecular mass of copper (II) sulphate crystals

Sagot :

Answer:

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

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 [tex]63.546+64+32.065 = 159.611[/tex] g/mol
