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 241.4 mL of gas with a total pressure of 1.34 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. How many grams of aluminum must have reacted to produce this quantity of hydrogen gas?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
