1. In this exercise, HCl was used in excess, making magnesium the limiting reactant. The mol of H2 calculated for the post-lab is the theoretical yield of H2. Choose two of your trials and calculate the actual yield of H2 using the ideal gas law and the volume, pressure, and temperature data from the exercise. Then calculate the percent yield. Trial Trial 2. Consider your results, percent errors, and percent yields from question 1 . Were you able to confirm that the molar volume of a gas at STP is 22.4L/mol ? Why or why not? Include at least one source of error as part of your answer.
