The anti-cancer drug m-THPC has an ? of 22,400 M^-1 cm^-1 at 652 nm in methanol. If I put a methanol solution of m-THPC into a 10.0 mm pathlength cuvet, and observe an absorbance of 0.132 (no units) at 652 nm, what is the concentration of the solution? (Assume there are no other solutes present in the methanlo.
