Question

Zinc reacts with hydrochloric acid to give hydrogen and zinc chloride. The volume of hydrogen gas produced at STP from the reaction of  of zinc with excess HCl is  L (Nearest integer). (Molar mass of Zn ; Molar volume of  at STP )

Canvas Classes · Accepted Answer

Strategy:
 stoichiometry of the reaction: . 1 mole of Zinc produces 1 mole of Hydrogen gas. Use the molar volume at STP to find the final volume.

Step 1: Calculate moles of Zinc

Step 2: Calculate volume of Hydrogen at STP
Given Molar Volume .

Nearest integer is 4.
