How to calculate concentration with just the absorbance and % transmittance measurements from a spectrometer? ​

Mathematics
1 answer:
Natali [406]3 years ago
8 0

Answer:

A=ε*l*c

A= 2- log₁₀ % T

Step-by-step explanation:

There is a linear relationship between the concentration of a sample and absorbance according to Beer-Lambert Law.

A=ε*l*c

where;

A=absorbance

ε=absorption coefficient

l=path length

c=concentration

Because % transmittance is transmittance value multiplied by 100 then, the equation that will allow us calculate absorbance from % transmittance value will be;

A= 2- log₁₀ % T where T is transmittance.

Number 25 someone help me
Fittoniya [83]
The area of a triangle is given by the formula A= \frac{1}{2}Bh, where B is the base and h is the height. We can rearrange this formula to solve for B.

\dfrac{A}{ \frac{1}{2}h} = B\\ \\\\\dfrac{2A}{h} = B.

We plug in the given area, 640 square millimeters, and the given height, 32 millimeters.

B= \dfrac{2(640)\ mm^2}{32 \ mm} = 40 \ mm.

40 mm is our final answer.
