Assignment:
A portable photometer with a linear response to radiation registered 73.6 μA with a blank solution in the light path. Replacement of the blank with an absorbing solution yielded a response of 24.9 μA. Calculate:
a) The percent transmittance of the sample solution.
b) The absorbance of the sample solution.
c) The expected transmittance if the concentration of absorber is one third that of the original solution.
d) The expected transmittance if the concentration of absorber is double that of the original solution.
Provide complete and step by step solution for the question and show calculations and use formulas.
