A student collects 69.2 mL of hydrogen gas from the reaction of 0.075 grams of magnesium solid with excess hydrochloric acid. The actual volume of hydrogen collected corrected to STP conditions is 62.5 mL. What would be the percent yield of hydrogen gas collected in this reaction. (HINT: you need to find the theoretical yield of hydrogen first.) The mole ratio of magnesium to hydrogen is 1:1.
