Chemistry Question on Stoichiometry and Stoichiometric Calculations

Question

Zinc reacts with hydrochloric acid to give hydrogen and zinc chloride The volume of hydrogen gas produced at STP from the reaction of $115 \, g$ of zine with excess $HCl$ is ___ $L$ (Nearest integer)
(Given: Molar mass of $Zn$ is $654 \,g \,mol ^{-1}$ and Molar volume of $H _2$ at $STP =227 \,L$ )

Accepted Answer

The correct answer is 4.
Zn+2HCl→ZnCl2+H2↑
Moles of Zn used =65.411.5= Moles of H2 evolved
Volume of H2=65.411.5×22.7L=3.99L
=4
