Answer:
Zn + H2SO4====> ZnSO4 + H2
1 Gram Atom of zinc- metal liberates 1- mole or 22400 ml of Hydrogen gas at STP.
ie., 65.38 g of zinc on Reaction with dil.sulphuric acid liberates 22400 ml of Hydrogen gas at STP.
So to produce 224 ml of Hydrogen at STPwe require =224/22400x65.38= 0.6538 g of zinc.
