calculate the mass of 3.5 moles of copper sulphate

Answer :

MEDUNNO13GO

Answer: 558.5545 g

Explanation:

The formula for a sulphate ion is [tex]\text{SO}_{4}^{\text{ }2-}[/tex], so the formula for copper sulphate is [tex]\text{CuSO}_{4}[/tex].

  • The atomic mass of copper is 63.546 g/mol.
  • The atomic mass of sulfur is 32.065 g/mol.
  • The atomic mass of oxygen is 15.994 g/mol.

This means the formula mass of copper sulphate is:

  • 63.546+32.065+4(15.994)=159.587 g/mol.

So, in 3.5 moles, the mass is (159.587)(3.5)=558.5545 g
