A portable photometer with a linear response top radiation registered 83.2 microamps with a blank solution in the light path. Replacement of the blank with an absorbing solution yielded a response of 451 microamps calculate
a. the percent transmittance and absorbance of the absorbing solution
b. the expected transmittance if the concentration of absorber is one-half that of the original solution
c. the transmittance to be expected if the light path through the original solution
