Experiment 19 Gas Stoichiometry and the Gas Laws The relationship between the physical properties of a gas, and the moles, is given by the “Ideal Gas Law:" PV=nRT where n-number of moles R=the ideal gas constant: 0.0821 atm L mole 'Kor 62.4 L torr molek In this experiment, the theoretical yield of gas, will be compared to the experimental yield. The reaction of aluminum with hydrochloric acid produces hydrogen according to the balanced equation below....
