Reference no: EM132508046

A photometer with a linear response to radiation gave a reading of 625 mV with a blank in the light path and 149 mV when the blank was replaced by an absorbing solution.

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 is doubles.
