What is the experimental molar mass (that is, calculated from the data given and not taken from the periodic table) of magnesium if 0.0316 grams of magnesium generates 31.53 mL of hydrogen at 22.6 °C with a hydrogen partial pressure of 762.6 torr? Note that the partial pressure of water vapor has already been subtracted from the total pressure. 23.1 g/mol 26.4 g/mol 24.2 g/mol 20.0 g/mol 26.2 g/mol

Given Mass= 0.0316 gram Temperature =22.6 °C = 295.75K Pressure=762.6 torr Volume =31.53 mL
