Question

A sample of 0.19 g mixture containing aluminum reacts with HCl(aq), 134 mL hydrogen gas (H₂)
produced is collected over water at 26 °C and a barometric pressure of 744 mmHg. Vapor pressure of water
at this temperature is 25.2 mmHg and only aluminum reacts in the mixture what is the percentage of
aluminum in the mixture?
2 Al(s) + 6 HCl(aq) → 2 AlCl₃(aq) + 3 H₂(g)

1. A sample of 0.19 g mixture containing aluminum reacts with HCl(aq), 134 mL hydrogen gas (H2)
produced is collected over water at 26 °C and a barometric pressure of 744 mmHg. Vapor pressure of water
at this temperature is 25.2 mmHg and only aluminum reacts in the mixture what is the percentage of
aluminum in the mixture?
2 Al(s) + 6 HCI(aq) → 2 AIC13(aq) + 3 H2(g)
