The combined gas law states that the pressure of a fixed mass of a gas is directly proportional to its absolute temperature and inversely proportional to volume at constant environmental conditions.
That is p α T/V, Thus, considering two gases P1V1/T1 =P2V2/T2,
Thus, V2= P1V1T2/T1P2
hence , final volume = 1.5 x 15.4 x 268/ 310 x0.9
= 22.189 liters
