    P₂ = 28.5 torr

    Explanation:

    Given dа ta:

    Initial pressure = 38 torr

    Initial volume = 500 L

    Final volume = 677 L

    Final pressure = ?

    Solution:

    P₁V₁ = P₂V₂

    P₁ = Initial pressure

    V₁ = Initial volume

    P₂ = Final pressure

    V₂ = Final volume

    Now we will put the vales in formula.

    P₁V₁ = P₂V₂

    P₂ = P₁V₁ / V₂

    P₂ = 38 torr * 500 L / 667 L

    P₂ = 19000 torr. L / 667 L

    P₂ = 28.5 torr
