| 1. Let’s compose the reaction equation:
Zn + H2TeO4 = ZnTeO4 + H2 ↑;
2.Calculate the chemical amount of zinc:
n (Zn) = m (Zn): M (Zn) = 45.5: 65 = 0.7 mol;
3. Determine the amount of hydrogen:
n (H2) = n (Zn) = 0.7 mol;
4.Calculate the volume of evolved hydrogen:
V (H2) = n (H2) * Vm = 0.7 * 22.4 = 15.68 liters.
Answer: 15.68 liters.
