How do I solve this
Hydrogen gas is produced by the reaction between metallic aluminum and aqueous hydrochloric acid.2Al(s)+6HCl(aq)⟶2AlCl3(aq)+3H2(g)The hydrogen gas produced by this reaction is typically collected via water displacement. During this process, the hydrogen gas becomes saturated with water vapor. If 292.0 mL of gas with a total pressure of 1.33 atm is collected via water displacement at 29.4 ∘C, what is the partial pressure of the hydrogen gas in the sample? The vapor pressure of water at 29.4 ∘C is 30.75 torr.
