We can use the ideal gas law equation; PV = nRT P - pressure, V - volume , R - universal gas constant, n - number of moles and T - temperature P - 1 atm - 101 325 Pa 1.09 atm - 1.09 atm x 101 325 Pa/atm = 110 444 Pa n - 0.175 mol V - 1.59 x 10⁻³ m³ substituting the values in the equation 110 444 Pa x 1.59 x 10⁻³ m³ = 0.175 mol x 8.314 Jmol⁻¹K⁻¹ x T T = 120.70 K
