    For this question we can use the ideal gas equation,

    PV = nRT

    P - pressure

    V - volume - 66.8 / 1000 m³

    n - number of moles - 77.8 g / 28 g/mol = 2.77 mol

    R - universal gas constant - 8.314 Jmol⁻¹K⁻¹

    T - 25 °C + 273 = 298 K

    substituting these values in the equation

    P x 0.0668 m³ = 2.77 mol x 8.314 Jmol⁻¹K⁻¹ x 298 K

    P = 102.7 kPa
