    0.0146cm^3

    Explanation:

    Using the combined Gas Law P1V1/t1 = P2V2 / t2

    P1 ... 0.934

    V1 ... 0.0148

    T1 ... 11° (284K)

    P2 = 0.974

    V2 = V2 (unknown)

    T2 = 20° (293K)

    Hence 0.934x 0.0148 / 284 = 0.974x V2 / 293

    0.000048 = 0.974V2 / 293

    0.000048 x 293 = 0.974V2

    0.01426=0.974V2

    V2 = 0.01426 / 0.974

    V2 = 0.0146 cm^3
