An alloy consists of aluminium and zinc. If 0.2500 g of the alloy reacts with HCl hydrogen gas is produced according to the following net ionic equations: Al (s) + 3 H+ (aq) = Al3+ (aq) +  3/2 H2 (g) Zn (s) + 2 H+ (aq) = Zn2+ (aq) + H2 (g) The hydrogen produced has a volume of 755 mmHg. Determine the percentage of zinc in the alloy

Question

An alloy consists of aluminium and zinc. If 0.2500 g of the alloy reacts with HCl hydrogen gas is produced according to the following net ionic equations:

Al (s) + 3 H+ (aq) = Al3+ (aq) +  3/2 H2 (g)

Zn (s) + 2 H+ (aq) = Zn2+ (aq) + H2 (g)

The hydrogen produced has a volume of 755 mmHg. Determine the percentage of zinc in the alloy.
