    P₂ = 0.7 atm.

    Explanation:

    Given data;

    Initial Volume = 310 mL

    Initial Pressure = 0.995 atm

    Final volume = 440 mL

    Final pressure = ?

    Solution;

    P₁V₁ = P₂V₂

    P₂ = P₁V₁/V₂

    P₂ = 0.995 atm. 310 mL / 440 mL

    P₂ = 308.45 atm. mL / 440 mL

    P₂ = 0.7 atm.
