    Volume = 0.14 L

    Explanation:

    This is a simple Molarity problem in which we are given with,

    Moles = 0.07 moles

    Molarity = 0.5 mol. L⁻¹

    Volume = ?

    Now, as,

    Molarity is the amount of solute dissolved per unit volume of solution. It is expressed as,

    Molarity = Moles / Volume of Solution

    So, Solving for Volume,

    Volume = Moles / Molarity

    Now, putting value of Moles and Molarity,

    Volume = 0.07 mol : 0.5 mol. L⁻¹

    Volume = 0.14 L
