Molar mass of Mathane = 16 g Moles = mass / molar mass = 1.6 g / 16 g/mol= 0.10 mol for carbon dioxide (molar mass = 44 g/mol) = 2.2 g / 44 g/mol = 0.05 mol Total number of moles = 0.15 mol of gas formula of PV = nRT so P = nRT / V n = 0.15 mol R = 8.31 kPa.L/mol.K T = 27°C = 300 K V = 9.0 L P = (0.15 mol)(8.31 kPa.L/mol.K)(300 K) / (9.0 L) = 41.5 kPa
