A flask with a volume of 3.16 L contains 9.33 grams of an unknown gas at 32.0$\degree$C and 1.00 atm. What is the molar mass of the gas?

To find the molar mass, use the ideal gas law: PV = nRT. First, convert the temperature to Kelvin (32.0 + 273.15 = 305.15 K). Rearrange the ideal gas law to solve for n (moles): n = PV/RT. Use R = 0.0821 L·atm/mol·K. Substitute P = 1.00 atm, V = 3.16 L, and T = 305.15 K to find n. Then, calculate the molar mass by dividing the mass of the gas (9.33 g) by the number of moles (n). The result is approximately 74.0 g/mol.
