The reaction of metallic aluminum with aqueous hydrochlotic acid produces hydrogen gas.

2Al + 6HCl --> 2AlCl3 + 3H2

Hydrogen gas produced by this reaction is typically collected via water displacement, during which time the hydrogen gas becomes saturated with water vapor. A 241.5 mL sample of gas with a total pressure 118 kPa was collected via water displacement at 29.4C. Calculate the partial pressure of hydrogen gas in the sample. The vapor pressue of water at 29.4C is 4.10 kPa.

Calculate the mass of aluminum that reacted to produce this quantity of hydrogen gas.

Small quantities of hydrogen gas can be prepared in the laboratory by the addition of aqueous hydrochloric acid to metallic zinc. Zn(s)+2HCl(aq)⟶ZnCl2(aq)+H2(g) Typically, the hydrogen gas is bubbled through water for collection and becomes saturated with water vapor. Suppose 240. mL of hydrogen gas is collected at 30.∘C and has a total pressure of 1.032 atm by this process. What is the partial pressure of hydrogen gas in the sample? How many grams of zinc must have reacted to produce this quantity of hydrogen? (The vapor pressure of water is 32 torr at 30∘C.)
