    V₂ = 4.343 L

    Explanation:

    Given dа ta:

    Initial pressure = 150 KPa (150/101.325 = 1.5 atm)

    Initial volume = 3.50 L

    Initial temperature = 330 K

    Final pressure = 1 atm

    Final temperature = 273 K

    Final volume = ?

    Formula:

    P₁V₁/T₁ = P₂V₂/T₂

    P₁ = Initial pressure

    V₁ = Initial volume

    T₁ = Initial temperature

    P₂ = Final pressure

    V₂ = Final volume

    T₂ = Final temperature

    Solution:

    V₂ = P₁V₁ T₂ / T₁ P₂

    V₂ = 1.5 atm * 3.50 L * 273 K / 330 K * 1 atm

    V₂ = 1433.25 atm. L. K / 330 K. atm

    V₂ = 4.343 L
