Thyroxine is an important hormone that controls the rate of metabolism in the body, and it can be isolated from the thyroid gland. When 0.455 g of thyroxine is dissolved in 10.0 g of benzene, the freezing point of the solution is 5.2 °C. What is the molar mass of thyroxine, assuming that it is a nonelectrolyte? Show the calculations please and briefly explain your answer

Potentially useful information about benzene:
C6H6, MM 78.12 g/mol m.p. 5.5 °C, b.p. 80.1 °C ,
Kf= 5.12 °C·kg/mol, Kb= 2.53 °C·kg/mol
