Which statement describes an experimental step(s) that is necessary to determine the molar mass using the freezing depression method? Determine the molar mass of the solute by looking up the elements in the periodic table. Measure the heat of fusion of the pure solvent and then measure the heat of fusion of the pure solute. Calculate the number of moles in a kilogram of solvent to determine its molality. Measure the freezing point of the pure solvent and then measure the freezing point of the solution
