Spectrophotometric Determination of a Food Dye
Part 2 of 2: Molar Absorptivity Coefficient
Use this page to check whether you have carried out the
calculation of the molar absorptivity coefficient in the
Spectrophotometric Determination of a Food Dye lab correctly.
This page does not tell you if your value
of the molar absorptivity coefficient is correct; it only tells
you whether the value you calculated is consistent with the data you
collected. Enter your data as indicated below, paying special
attention to the indicated units. Enter values of %T as
percents; for example, use 51.3% instead of 0.513.
When you have entered all of the data, select "Check
Calculation". You will be told how close your calculated value
is to the value calculated by the computer.
