    The volume of ideal gas that would occupy at 1.50 atm and 216 c is

    2016.49 ml

    calculation

    volume is calculated using a combined gas equation

    that is P1V1/T1 = P2V2/T2

    P1 (pressure 1) = 7.20 atm

    V1 (volume 1) = 250 ml

    T1 (temperature 1) = 18 + 273=291 K

    P2 (pressure 2) = 1.50 atm

    T2 (temperature 2) = 216+273=489 K

    V2 (volume 2) = ?

    by making V2 the subject of the formula

    V2=[ (T2 xP1 x V1) / (T1 xP2) ]

    V2=[ (489 K x 7.20 atm x 250 ml) / (291 k x 1.50 atm) ] = 2016.49 Ml
