Determining the

Question

transmittance (T) or %T
• Calculate the %T for a sample it its absorbance
is 1.27.

Answer 1

To calculate the %T, you can use the formula:

%T = 10^(-Absorbance) * 100

Given that the absorbance is 1.27, plug it into the formula:

%T = 10^(-1.27) * 100
%T = 10^(-1.27) * 100
%T = 0.05011872336 * 100
%T ≈ 5.01%

So, the transmittance of the sample is approximately 5.01%.
