Thyroxine, an important hormone that controls the rate of metabolism in the body can be isolated from the thyroid gland. If 0.455 g of thyroxine is dissolved in 10.0 g of benzene, the freezing point of the solution could be measured as 5.144C. Pure benzene freezes at 5.444C and has a value for the molal freezing-point-depression constant of Kf of 5.12C/m. What is the approximate molar mass of thyroxine?
