A photometer with a linear response to radiation gave a reading of 498 mV withthe solvent in the light path and 25fl mV when the solvent was replaced by anabsorbing solution. The photometer was set to zero with no light striking thedetector. Calculate(a) the percent transmittance and absorbance of the absorbing solution.(b) the expected transmittance if the concentration of absorber is one half thatof the original solution.(c) the transmittance to be expected if the light path through the originalsolution is doubled.
