Ex.1. Potassium chromate in the base solution shows the highest absorption at 372 nm, so the titrating of a base solution contains 3x 10-5 molar of K2CrO4with a transmittance of %71.6 from the intensity of the incident radiation at 372 nm when placed in a 1 cm absorbance measurement cell. Find the following : 1. The absorbance value of this solution 2. The molarity absorbance of potassium chromate at 372 nm 3. The %T when the absorption cell length becomes 3 cm bars
