How to calculate concentration with just the absorbance and % transmittance measurements from a spectrometer? ​
Natali [406]

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.

A midsegment is given by the formula:
\frac{x1+x2}{2} , \frac{y1+y2}{2}

Where x1, x2, y1, and y2 correspond to their respective coordinates. We can do the equation:

\frac{-3+5}{2} , \frac{-1+3}{2}
This gets us a midpoint coordinate of <span>(1,1)

</span>As for distance, it will be found by doing:
\sqrt{(x2-x1)^2+(y2-y1)^2}
We can do the following:

\sqrt{(5-(-3))^2+(3-(-1))^2}
\sqrt{(8)^2+(4)^2}
\sqrt{64+16}
This simplifies to 4 \sqrt{5}

Find the slope of the line through the pair of points.
erastovalidia [21]

Answer:

The answer is A undefined

Step-by-step explanation:

The slope is given by

m=\frac{y_{2}-y_{1} }{x_{2}-x_{1}  }

m=\frac{9-(-13)}{17-17}=\frac{22}{0}

which is undefined (division by zero)
