    0.162 M

    Explanation:

    We are given;

    Initial concentration as 18.0 M Initial volume of the solution is 18.0 mL or 0.018 L Final volume of the solution is 2.0 L

    We are required to find the final concentration or molarity.

    When a solution is diluted by adding more solvent, the concentration of the solution decreases. To find the final concentration of the dilute solution we use the dilution formula, C1V1 = C2V2.

    Rearranging the formula;

    C2 = C1V1 : V2

    = (18 M * 0.018 L) : 2.0 L

    = 0.162 M

    Therefore, the final concentration will be 0.162 M
