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 .
