If the absorbance of the 10μM solution is 0.24, what should be the absorbance of the 50μM? Write answer to two decimal places.

Absorbance/Concentration = Constant.

That is, absorbance is directly proportional to concentration.

Therefore,

0.24/10 = x/50, where x is the absorbance at 50 micro m.

Calculating for x;

x=50 * (0.24/10) = 1.20 (correct to 2 decimal places)
