To solve the problem step by step, we will follow the stoichiometric relationships in the reaction between zinc and sulfuric acid. ### Step 1: Write the balanced chemical equation The reaction between zinc (Zn) and sulfuric acid (H₂SO₄) can be represented as: \[ \text{Zn} + \text{H}_2\text{SO}_4 \rightarrow \text{ZnSO}_4 + \text{H}_2 \] ### Step 2: Determine the molar masses - Molar mass of Zinc (Zn) = 65.4 g/mol ...
