A reaction of 0.0320 g of magnesium with excess hydrochloric acid generated 31.21 mL of gas. The gas was
collected by water displacement in a 22 oC water bath. The barometric pressure in the lab that day was 736
mmHg.
1. Write the balanced chemical equation for this reaction.
2. What is the theoretical number of moles of hydrogen that can be produced from 0.032 g of Mg?
3. Use Dalton’s law and the vapor pressure table to calculate the partial pressure of hydrogen gas in the
collecting tube.
4. Use the ideal gas law to calculate the moles of hydrogen gas actually produced.
5. Calculate the percent yield of moles of hydrogen gas produced
