A solution of I2, in ethanol had a density of 0.794 g/cm3. A 1.50-cm layer was found to transmit 27.3% of the radiation from a Mo Ka source. Mass absorption coefficients for I. C, H, and O are 39.2,0.70.0.00, and 1.50, respectively.

(a) Calculate the percentage of I2, present, neglecting absorption by the alcohol.

(b) Correct the results in part (a) for the presence of alcohol.
