A mixture of compounds X and Y in a 0.100-cm cell had an absorbance of 0.215 at 272 nm and 0.191 at 327 nm. Find [X] and [Y] in the mixture. (Enter unrounded values.)

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 .

the answer would be 150 books

step-by-step explanation:

if you divide 300 by 2 you will get 150

hello,

as   long as they add up to 180 its correct.
