Explain the molecular weight for chlorophyll

Reference no: EM13253209

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.

If the molar concentration of the solution is .00000387, then what is the concentration of the solution in ppm (parts per million)?
