    14 milliliters

    Explanation:

    We are given;

    10.0 M HNO₃

    Prepared solution;

    Volume of solution as 0.350 L Molarity as 0.40 M

    We are required to determine the initial volume of HNO₃

    We are going to use the dilution formula; The dilution formula is;

    M₁V₁ = M₂V₂

    Rearranging the formula;

    V₁ = M₂V₂ : M₁

    = (0.40 M * 0.350 L) : 10.0 M

    = 0.014 L

    But, 1 L = 1000 mL

    Therefore,

    Volume = 14 mL

    Thus, the volume of 10.0 M HNO₃ is 14 mL
