    406.45mL

    Explanation:

    The following data were obtained from the question:

    V1 = 350mL

    P1 = 720mmHg

    P2 = 630mmHg

    V2 = ?

    The new volume can be obtain as follows:

    P1V1 = P2V2

    720 x 350 = 620 x v2

    Divide both side by 620

    V2 = (720 x 350) / 620

    V2 = 406.45mL

    The new volume of the gas is 406.45mL
