    The answer to your question is P2 = 170.9 torr

    Explanation:

    Data

    Volume 1 = 12.1 l Volume 2 = 21.1 l

    Temperature 1 = 241 °K Temperature 2 = 298°K

    Pressure 1 = 546 torr Pressure 2 = ?

    Process

    To solve this problem use the combined gas law.

    P1V1/T1 = P2V2/T2

    -Solve for P2

    P2 = T1V1T2 / T1V2

    -Substitution

    P2 = (241 x 12.1 x 298) / (241 x 21.1)

    -Simplification

    P2 = 868997.8 / 5085.1

    -Result

    P2 = 170.9 torr
