Questions & Answers

QUESTION:

Calculate the absorbance of solul ions having twice the percent transmittance ofthose in 13-2.

ANSWER:

Absorbance is defined as the amount of light absorbed by the sample substance. It is also known as optical density. The absorbance of a solution is calculated from the percent transmittance by the formula given below:

, Where, T is transmittance.

Step 1 of 3

a) Transmittance=31.6% =0.316

On substituting the value in the above equation, we get

b) Transmittance=0.984%=0.00984

On substituting the value in the above equation, we get
