Using the ideal gas law, PV = nRT, we can solve for the molar mass (M). First, convert 27°C to Kelvin (300 K). Then, use R = 0.0821 L·atm/mol·K. Calculate n = PV/RT = (2.2 atm)(3.0 L) / (0.0821 L·atm/mol·K)(300 K) = 0.268 mol. Molar mass M = mass/n = 16 g / 0.268 mol = 59.7 g/mol, which rounds to 60 g/mol.
