Explain the absorbance of a chlorophyll a standard solution

Reference no: EM13252934

The absorbance of a chlorophyll a standard solution in ethanol (density = 0.785 g/mL) is measured in a 1.3 cm cuvette or path length. The absorbance is 0.435 and the molar absorptivity coefficient is 86,300 M-1cm-1. The molecular weight for chlorophyll a is 893.49 g/mol.

A) What is the molar concentration of the solution?

B) What is the concentration of the solution in ppm?
