transcribed:A solution of a specific vitamin has a max of 223 nm and a concentration of 7.36×10−7M. The absorbance of the solution at 223 nm is =0.160.
What is the molar absorptivity of the vitamin at 223 nm ? A sample path length is 1.00 cm.

To solve this problem, we use the Beer-Lambert's Law this relates absorbance and concentration of the species that is absorbing light. It is expressed as A = eCl where e is the molar absorptivity, C is the concentration and l is the path length.

A = eCl

0.150= e(2.71x10^-7 M)(1.00 cm)

e = 553505.5351 L / mol-cm
