A sample of unknown concentration is diluted by placing 0.2 mL into 9.8 mL of buffer and then 3 mL is placed into a standard 1x1

Lina20 [59]

Answer:

The answer is " $4.875 \ \frac{mol}{l}\\$ ".

Explanation:

The molar absorptivity value is= 12.3 $\frac {L}{mol \times cm}$

path length of cell = 1 $\ cm$

Absorbance = 1.2

Using the beer's lambert law:

$A = \varepsilon \ cl\ \ \ \ \ \ \ _{where} \\\\c= \frac{A}{ \varepsilon l } \\\\$

$= \frac{1.2}{12.3 \times 1}\\\\= 0.0975 \ \frac{mol}{L}\\$

Claculating the concentration of the solution after dilution: $(m_2)= 0.0975 \ \ \frac{mol}{L}$

find out the dilution value before concentration :

The volume taken by the dilution: $(V_1) = 0.2\ ml$

The final volume after dilution:

$(V_2) = 9.8+0.2\\$

$= 10 \ ml$

Formula:

$\bold{M_1 \times V_1 = M_2 \times V_2} \\\\ M_1= \frac{M_2 \times V_2 }{V_1}\\\\$

$= \frac{ 0.0975 \times 10 }{0.2}\\\\= \frac{ 0.975 }{0.2}\\\\ = 4.875 \ \frac{mol}{l}\\$

Evolution is change in a population over time and includes the gene pools of that population. How does biogeographic isolation a

jonny [76]

Correct answer: A) bio-geographic isolation affects the random changes that take place within gene pools

The bio-geographic isolation of the species takes place when the geographical barrier work as a distinguishing agent. It takes place when the group of animals, plants and other creatures are not allowed to mate with each other.

The mixing of there genes within the same species is separated by the geographical barrier.

The barrier allows the mating of the species in a different way as compared to the previous one.
