You have isolated compound X from panda pancreas. You started with a whole pancreas, and finished up with 5 ml of a pure solution of X. You take 200 µl of this solution, and add it to 1.8 ml of buffer. The absorbance of this dilute solution at 340nm was 0.732. The molar extinction coefficient at 340nm for compound X is 12,400 l/mol cm. The formula weight of compound X is 14,200 g/mol How many total mg of X are there in the panda pancreas?
