Answer: The concentration of X is
and the concentration of Y is
.
Step-by-step explanation:
Since we have given that
At 272 nm, absorbance = 0.215
At 327 nm, absorbance = 0.191
As we have given that
Compound X Compound Y
272 16400 3870
327 3990 6420
So, our equations becomes

By solving these two equations, we get that

Hence, the concentration of X is
and the concentration of Y is
.
Answer:
3(10)-7
Step-by-step explanation:
3(10)-7
Change 15% into a decimal
15% = 15/100 = 0.15
multiply 0.15 and 205,000 together
205000 x 0.15 = <span>30750
$30,750 is your answer
