    To determine the temperature of the gas, we need to assume ideal gas to use the equation PV=nRT where P represents the pressure, V is the volume, n is the number of moles, T is the temperature and R is the universal gas constant. We calculate as follows:

    PV = nRT

    T = PV / nR

    T = (1.26 atm) (208 L) / 0.08205 L-atm/mol-K (9.95 mol)

    T = 321.02 K

    Hope this answers the question.
