    Answer:

    9.91 mL

    Explanation:

    Using the combined gas law equation as follows;

    P1V1/T1 = P2V2/T2

    Where;

    P1 = initial pressure (torr)

    P2 = final pressure (torr)

    V1 = initial volume (mL)

    V2 = final volume (mL)

    T1 = initial temperature (K)

    T2 = final temperature (K)

    According to the information provided in this question;

    V1 = 15.0mL

    V2 = ?

    P1 = 760 torr

    P2 = 1252 torr

    T1 = 10°C = 10 + 273 = 283K

    T2 = 35°C = 35 + 273 = 308K

    Using P1V1/T1 = P2V2/T2

    760 × 15/283 = 1252 × V2/308

    11400/283 = 1252V2/308

    Cross multiply

    11400 × 308 = 283 × 1252V2

    3511200 = 354316V2

    V2 = 3511200 ÷ 354316

    V2 = 9.91 mL
