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.

3 to the 5th power.....when you multiply you add the exponents
Answer:
Step-by-step explanation:
The explicit formula for a geometric sequence:
- n-th term
- first term
- common ratio
We have
The common ratio:
<h2>It's not a geometric sequence.</h2>
If then the common ratio is
Put to the explicit formula:
Put and solve for <em>n </em>:
Answer:
30 and -30 and if that doesn’t work then maybe try -30 first and 30 next
