6.54g of Zn is dissolved in excess of H₂ SO₄. The weight of ZnSO₄ formed and the volume of H₂ gas liberated at STP are ( molar mass of Zn=65.4 g)

A. 16.14g, 11.2 L

B. 16.14g, 22.4 L

C. 161.4g, 2.24 L

D. 16.14g, 2.24 L

E. None of the above

View Answer

Correct choice: D

Explanation:

Zn + H₂ SO₄ → H₂ +ZnSO₄
1mole i.e 65.4 gm of Zn gives 1mole i.e 161.4 gmof ZnSO₄ and 22. 4 lit H₂ at STP
6.54 gm of Zn gives 16.14 gmof ZnSO₄ and 2 .24 lit H₂ at STP
