Question: A solution was prepared by dissolving 118.9 mg of K2Cr2O7 in 1.000 L of water. A 10.00 mL aliquot was transferred to a 100.0 mL
A solution was prepared by dissolving 118.9 mg of K2Cr2O7 in 1.000 L of water. A 10.00 mL aliquot was transferred to a 100.0 mL volumetric flask and diluted to the mark. The dilute solution had an absorbance of 0.206 at 400 nm, in a 1.00 cm cell.
(i) What is the concentration of the dilute solution in ppm?
(ii) Using Beers Law equation, calculate the molar absorptivity of K2Cr2O7
