    a) 23.2 L

    b) 68.3kPa

    c) 7.5 atm

    d) 60.5L

    e) 1.67 atm

    Explanation:

    From Boyle's law:

    P1V1=P2V2

    P1 = 748mmHg

    P2=725mmHg

    V1 = 22.5L

    V2?

    V2 = P1V1/P2 = 748*22.5/725 = 23.2 L

    b)

    V1=4.0L

    P1 = 205*10^3Pa

    V2 = 12.0L

    P2=?

    P2 = P1V1/V2 = 205*10^3*4/12

    P2 = 68.3*10^3 Pa or 68.3kPa

    c)

    P1 = 1 atm

    V1 = 196.0L

    P2=?

    V2 = 26.0L

    P2 = P1V1/V2=1*196.0/26.0

    P2 = 7.5 atm

    d)

    V1 = 40.0L

    P1 = 12.7*10^3Pa

    V2=?

    P2 = 8.4*103Pa

    V2 = P1V1/P2 = 12.7*10^3*40.0/8.4*103

    V2=60.5L

    e)

    V1 = 100mL

    P1 = 1atm

    V2 = 60mL

    P2=?

    P2 = P1V1/V2 = 1*100/60

    P2 = 1.67 atm
