Reaction of 0.028 g of magnesium with excess hydrochloric acid generated 31.0 ml of hydrogen gas. the gas was collected by water displacement at 22 degree c. the barometric pressure in the lab was 746 mm hg. the vapor pressure of water at 22 degree c is 19.8 mm hg. use dalton's law to calculate the partial pressure of hydrogen gas in the gas-collecting tube. use the combined gas law to calculate the volume of hydrogen at stp. what is the theoretical number of moles of hydrogen that can be produced from 0.028g of mg?
