The molar mass of a gas is determined as in the experiment

Last updated: 7/9/2022

The molar mass of a gas is determined as in the experiment described in Experiment 8. The mass is determined to be 2.01 g. The volume of the water, which is equal to the volume of the gas, is measured to be 243 mL, the boiling water temperature was 99.8°C and the barometric pressure was 755 mm Hg. Calculate the molar mass of the gas. Use 0.0821 L-atm/mol-K as the value of the ideal gas law constant, R. Enter the value of your answer only. The value you enter should be expressed in g/mol.
