SUMMARY
The molar mass of an unknown gas can be calculated using Graham's Law of Effusion. In this discussion, it is established that a 10.0 mL sample of helium (He) effuses in 5.00 minutes, while the unknown gas takes 16.6 minutes. By applying the formula derived from Graham's Law, the molar mass of the unknown gas is determined to be approximately 40.0 g/mol.
