The Ideal Gas Law and Reaction Stoichiometry

37

• Use the ideal gas law to convert gas variables (P, T, and V) to  moles of gaseous reactants and products.

• In reactions involving gases, we usually measure their volume,  temperature, and pressure rather than their mass.

Problem: A method for reducing a metal oxide is to heat it with H 2 forming metal and water. What volume of H 2 at 765 torr and 185 ƒC is needed to form 35.5 g Cu from copper(II) oxide?
