Question

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

Answer 1

Absorbance is directly proportional to concentration.

Therefore,

0.24 ---- 10 micro m
x ---- 50 micro m Where x= absorbance at a concentration of 50 micro m.

Then
x= (0.24*50)/10 = 1.2

To two decimal places,
x=1.20
