Explanation / Answer

A fixed quantity of gas at 22°Cexhibits a pressure of 726 torr andoccupies a volume of 5.45 L. a)using Boyles law: i.e P1V1 = P2V2 we have V2 = P1V1/P2 now 1 atm = 760 torr so 1.82 atm = 1.82* 760 torr                    = 1383.2 torr                    = 726 torr * 5.45L / 1383.2 torr                      = 2.86 L b)using Charles law i.e V1/T1 = V2/ T2 we have V2 = V1*T2/T1 now T1 = 22 degress C            = 22+ 273 K             = 295 K T2 = 180 degrees C      = 180 + 273 K       = 453 K and V1 = 5.45 L so V2 = 8.3689 L
