A gas cylinder of volume 26 liters contains an ideal gas at temperature 27 degrees C and pressure 1920 kPa. Some of the gas leaks until the pressure falls to 1500 kPa. How many moles of gas leaked, assuming that the temperature remains constant during this process?

  1. P V = n R T

    Final state:
    P = 1.5*10^6 N/m^2
    V = 26 liters = 26*10^-3 m^3
    T =273+27 = 300 K
    so
    n R = PV/T = 1.5*26*10^3/300
    = .13 * 10^3
    R =8.314
    so
    n = .13*10^3/8.314 = 15.6 moles

    Do that again for 1.92*10^6 N/m^2
    and get a bigger initial n

    then subtract

  5. 1.92 /1.5 = 1.28

    1.28* 15.6 = 19.97

    19.97 - 15.6 = 4.37
