What is the experimental molar mass (that is, calculated from the data given and not taken from the periodic table) of magnesium if 0.0199 grams of magnesium generates 19.21 mL of hydrogen at 20.2 °C with a hydrogen partial pressure of 775.0 torr? Note that the partial pressure of water vapor has already been subtracted from the total pressure.
