Description : How do I use this molar extinction coefficient?
Last Answer : answer:Molar extinction coefficients are typically in M^-1* cm^-1 (aka 1/(M*cm)). If using a cuvette with a 1 cm path length, using the equation you give above the cm cancels and it gives you concentration in ... b = cm, cm cancels, and M^-1 is in the denominator and thus c is left to simply be M.
