Hydrogen gas is produced by the reaction between metallic aluminum and aqueous hydrochloric acid.   2Al(s)+6HCl(aq)⟶2AlCl3(aq)+3H2(g)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 285.4 mL of gas with a total pressure of 1.44 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. ?H2= ________ atm How many grams of aluminum must have reacted to produce this quantity of hydrogen gas?   mass of aluminum: ______ g

Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".
