    We will assume helium to behave as an ideal gas and apply the ideal gas law:

    PV = nRT

    For pressure measured in atmospheres and volume measured in liters, the value of the molar gas constant is 0.082. Therefore:

    T = PV / nR

    T = (2.57 x 15.5) / (1.2 x 0.082)

    T = 404.8 Kelvin
