    Answer:

    1.27g/L is the new solubility when the pressure is increased

    Explanation:

    Based on Henry’s law, the solubility of a gas is directly proportional to the partial pressure of the gas in equilibrium.

    The equation is:

    S1 / P1 = S2 / P2

    Where S is solubility and P the pressure of 1, initial state and 2, final state.

    The values of the problem are:

    S1 = 0.22g/L

    P1 = 20.0kPa

    S2 = 115kPa

    P2 = ?

    0.22g/L / 20.0kPa = S2 / 115kPa

    S2 = 0.22g/L* 115kPa  / 20.0kPa

    S2 = 1.27g/L is the new solubility when the pressure is increased
