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.
Answer:
D
Step-by-step explanation:
So we have the expression:
And we want to evaluate it when x=25, y=10, w=11, and z=18.
So, substitute these values for the variables:
First, subtract within the parentheses:
Square 15:
Now, multiply the terms on the right. 10 times 11 is 110:
Multiply:
Finally, add:
So, our answer is D.
And we're done!
