0.235 grams of magnesium reacts with excess hydrochloric acid to make 309ml of hydrogen gas at 28°c and 615 mmhg. (the vapor pressure of water at
28 c is 28.3 mmhg). from the experimental data what is the molar mass(molar mass is the number of grams that are in 1 mol) of magnesium? (the
number of moles of mg that react are the same as the number of moles of
hydrogen gas that are produced.]
