Thyroxine, an important hormone that controls the rate of metabolism in the body, can be isolated from the thyroid gland. When 2.50 g thyroxine is dissolved in 55.0 g benzene, the freezing point of the solution is depressed by 0.300oC. What is the molar mass of thyroxine? (Kf for benzene is 5.12oC∙kg/mol.)

7. The vapor pressure of water at 25.0°C is 23.8 torr. Determine the mass of glucose (molar mass = 180 g/mol) needed to add to 500.0 g of water to change the vapor pressure to 23.3 torr. (20 points) 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 is found to...
