Question 30

Zinc reacts with an excess of dilute hydrochloric acid.

$Zn+2HCl→ZnCl2+H2\text{Zn} + 2\text{HCl} \rightarrow \text{ZnCl}_2 + \text{H}_2$

0.65 g of zinc reacts completely. The relative atomic mass of zinc is 65. The volume of one mole of any gas at room temperature and pressure is 24 dm³.

What is the volume of hydrogen produced at room temperature and pressure?
