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:

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

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

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.

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

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.

How would you explain the “density of the elephant population” to someone?

cricket20 [7]

Answer:

The most effective experimental approach to assess the effects of elephant impact on vegetation is to assess plant responses under differences in elephant density. It is important that other factors, such as soils or habitat structure are held constant so that the only factor which varies is elephant density.

What is the relationship between natural selection and adaptation ?

hoa [83]

Answer:

The difference between adaptation and natural selection is that adaptation is the characteristic while natural selection is the mechanism that increases the probability that an advantageous characteristic is passed on and becomes commonplace.
