Calculate pressure using the ideal gas law and the van der Waals equation. A 1.88-mol sample of argon gas is maintained in a 0.608-L container at 297 K. Calculate the pressure of the gas using both the ideal gas law and the van der Waals equation (van der Waals constants for Ar are a = 1.35 L²atm/mol² and b = 3.22×10-2 L/mol). Pideal gas equation = Pvan der Waals = atm atm

Use Graham's law of effusion to calculate molar mass.
A sample of krypton, Kr, effuses through a small hole at a rate of 9.00×10-6 mol/h. An unknown gas, under the same conditions, effuses at a rate of 1.93×10-5 mol/h.
Calculate the molar mass of the unknown gas.
