    Final volume = 71 L

    Explanation:

    Since the question involves volume and pressure, we use Boyle's law which states that

    P1V1 = P2V2;

    Where P1 and P2 are initial and final pressure respectively, and V1 and V2 are initial and final volumes respectively.

    P1 = 50 atm, P2 = 14 atm, V1 = 20 L, V2 = ?

    V2 = P1V1/P2

    V2 = (50 * 20) / 14

    V2 = 71 L
