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>

The motion permitted at a joint ranges from ____________ , such as where some skull bones interlock at a suture, to ____________
Elenna [48]
The correct answers are no movement; extensive movement.
You cannot move the joints near your skull - at least now willingly - only a doctor can remove parts of your skull if you are undergoing a brain surgery. Otherwise, there is no movement at all there. However, when it comes to your shoulders, for example, you can move them at will in whichever way you want to.
