Dissolving 7.55 mg of the steroid hormone estradiol (a predominantly nonpolar, molecular solute) in 0.500g of camphor (a nonpolar, organic solvent) changes the freezing temperature of the camphor by -2.10°C. Given camphors freezing-point depression constant of -37.7°C/m, calculate the molar mass of estradiol.
