    6.0 L

    Explanation:

    For this question, we can use

    P1*V1 = P2 * V2

    where

    P1 (initial pressure) = 0.2 kPa

    V1 (initial volume) = 15L

    P2 (final pressure) = 0.5 kPa

    V2 (final volume) = ?

    Since we are trying to find final volume, we can rearrange the equation to make V2 the subject.

    V2 = (P1 * V1) / P2

    V2 = (0.2 * 15) / 0.5

    V2 = 6 L
