Answer:
941 g
Explanation:
Step 1: Write the balanced equation
Zn + 2 HCl ⇒ ZnCl₂ + H₂
Step 2: Calculate the moles corresponding to 14.5 g of H₂
The molar mass of H₂ is 1.01 g/mol.
14.5 g × 1 mol/1.01 g = 14.4 mol
Step 3: Calculate the number of moles of Zn required to form 14.4 moles of H₂
The molar ratio of Zn to H₂ is 1:1. The moles of Zn required are 1/1 × 14.4 mol = 14.4 mol.
Step 4: Calculate the mass corresponding to 14.4 moles of Zn
The molar mass of Zn is 65.38 g/mol.
14.4 mol × 65.38 g/mol = 941 g
