    112.62 mL.

    Explanation:

    Suppose the temperature is constant.

    Boyle's Law states that at constant temperature, the volume of a given quantity of a gas varies inversely with its pressure.

    ∴ P₁V₁ = P₂V₂.

    P₁ = 91.0 kPa & V₁ = 125.0 mL.

    P₂ = 101.0 kPa & V₂ = ? mL.

    ∴ V₂ = (P₁V₁) / P₂ = (91.0 kPa) (125.0 mL) / (101.0 kPa) = 112.62 mL.
