Two solutions will be prepared with the mixture of distilled water and stock solution of KMnO4 (10 mM). Give the correct volumes
Yanka [14]

Answer:

See the answer below

Explanation:

<em>Recall that the law of dilution states that the number of moles before dilution must be equal to the number of moles after dilution.</em>

Mathematically,

     molarity x number of moles before dilution = molarity x number of moles after dilution.

For solution A: final molarity = 3 mM, final volume = 2mL, initial molarity of KMnO4 = 10 mM

Applying the equation:

    10 x initial volume = 3 x 2

        initial volume = 6/10 = 0.6

<u>Hence, Tube A should be made with 0.6 mL of 10 mM KMnO4 stock and  1.4 mL of distilled water to give a solution of 2 mL 3 mM KMnO4.</u>

For solution B:final molarity = 8 mM, final volume = 2 mL, initial molarity = 10 mM

    10 x initial volume = 8 x 2

       initial volume = 16/10 = 1.6

<u>Hence, Tube B should be made with 1.6 mL of 10 mM KMnO4 stock and 0.4 mL of distilled water to give a solution of 2 mL 8mM KMnO4. </u>
