Chemistry Question from JEE Main 2023 · 31 January, Shift 1

Zinc reacts with hydrochloric acid to give hydrogen and zinc chloride. The volume of hydrogen gas produced at STP from the reaction of 11.5 g11.5 \, \text{g} of zinc with excess HCl is \hspace{2cm} L (Nearest integer).

Given: Molar mass of Zn=65.4 g mol−1,Molar volume of H2 at STP=22.7 L/mol\text{Molar mass of Zn} = 65.4 \, \text{g mol}^{-1}, \quad \text{Molar volume of H}_2 \, \text{at STP} = 22.7 \, \text{L/mol}
