    The recommended way of preparing 100ml of 0.02 M from 2M NaOH in the laboratory is to obey the equation V1S1=V2S2.

    Explanation:

    According to the given question

    V2=100ml

    S2=0.02M

    S1 = 2M

    Then V1=?

    We all know that V1S1=V2S2

    or V1=V2*S2:S1

    or V1 = 100*0.02:2

    or V1 = 1 ml

    It can be concluded that 1ml of 2M NaOH solution and 99 ml distilled water should be mixed to prepare 100ml of 0.02 M NaOH solution.
