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.
⇒ 100 g of CuSO4 will contain of copper.
                          =
                          = 39.81 g 
Amount of copper that can be obtained from 100 g CuSO4  = 39.81 g

    Just a note that this calculation is for anhydrous CuSO4. The common blue pentahydrate form has mole weight of 249.7g.
