To find the pressure, use the ideal gas law: PV = nRT. First, convert 4.2 g of O2 to moles (4.2 g / 32 g/mol = 0.13125 mol). Convert 27 °C to Kelvin (27 + 273 = 300 K). Use R = 0.0821 L·atm/mol·K. Plug in the values: P(4.0 L) = (0.13125 mol)(0.0821 L·atm/mol·K)(300 K). Solving for P gives approximately 0.81 atm.
