    6.07 L

    Explanation:

    It appears that the reading has been made at constant pressure.

    At constant pressure, the gas law formula is

    V/T = constant V is volume and T is temperature of the gas.

    V₁ / T₁ = V₂ / T₂

    V₁ = 6.6 L,

    T₁ = 40°C

    = 273 + 40

    = 313 K

    T₂ = 15 + 273

    = 288K

    V₂ = ?

    Putting the values in the formula above

    6.6 / 313 = V₂ / 288

    V₂ = 6.07 L.
