Find the volume from the 0.450 moles gas at 200kpa and 300K temperature.

We assume the gas is an ideal gas therefore we can use the ideal gas equation to solve the problem. The ideal gas equation is expressed as PV = nRT where P is the pressure, V is the volume, n is the number of moles, R is the universal gas constant and T is the temperature.

V=nRT/P = 0.450 x 8314.472 x 300 / 200

V=5612.27 cm^3
