How much copper can be obtained from 100 g of copper sulphate (CuSO4 )?



Q.7:- How much copper can be obtained from 100 g of copper sulphate (CuSO4 )?

 

 

Answer:-



1 mole of CuSO4 contains 1 mole of copper.
Molar mass of CuSO4 = (63.5) + (32.00) + 4(16.00)
= 63.5 + 32.00 + 64.00 = 159.5 g
159.5 g of CuSO4 contains 63.5 g of copper.
∴ copper can be obtained from 100 g of copper sulphate = (63.5/159.5)×100 = 39.81g
