which of the following would cause the molar mass calculated from freezing-point depression data to be greater than the true molar mass? select one: some of the solute was spilled on the lab bench when being added to the solvent. the true mass of the solvent is less than the measured mass of the solvent. some of the solute particles break apart. all of these. water is added to the solvent after the freezing point of the pure solvent is determined.
