Problem- The weight of the tomato paste used was 15 grams, after distillation the final product came to be .500 grams. The solution was contained in a 1.00 cm cuvette (pathlength) and was placed in a spectrophotometer. It was found that the absorbance at the wavelength 467nm is 0.212.

Calculate the Molar absorptivity, Calculate the Molar concentration (C), and Calculate the % of carotenoid in your sample, based on the tomato paste weight and the weight of the final product in the distilling flask.

Depict your all calculation in detail so I can understand the solution thoroughly
