the pressure of the container can be calculated using the ideal gas law equation PV = nRT where P - pressure V - volume - 4.72 L n - number of moles - 0.023 mol R - universal gas constant - 0.0821 L.atm /mol.K T - temperature in kelvin - 105 °C + 273 = 378 K substituting the values in the equation P x 4.72 L = 0.023 mol x 0.0821 L.atm /mol.K x 378 K P = 0.151 atm pressure is 0.151 atm
