Question

how to find the percent transmittance?

Answer 1

\[\frac{ I }{ {I}_0 }\]

Answer 2

I0 is the intensity of incident radiation on the sample, and I is the emitted radiation

Answer 3

so if the abosirbance of the solution is 0.721at 520 mn, the percent of transmittance would be 19.01%?

Answer 4

absorbance is 1 - transmittance

Answer 5

i do not understand
