If an organic compound is a nonelectrolyte, it means that it does not dissociate into ions when dissolved in water. As a result, the compound does not contribute any charged particles to the solution.
The molar mass of a nonelectrolyte can be determined by measuring the freezing point depression or the boiling point elevation when a known mass of the compound is added to a solvent.
The formula to calculate the molar mass (M) of a nonelectrolyte using the freezing point depression (ΔTf) is:
M = (Kf * w) / ΔTf
Where: Kf is the cryoscopic constant of the solvent, w is the mass of the nonelectrolyte compound added, and ΔTf is the change in freezing point caused by the addition of the compound.
Similarly, for boiling point elevation, the formula is:
M = (Kb * w) / ΔTb
Where: Kb is the ebullioscopic constant of the solvent, and ΔTb is the change in boiling point caused by the addition of the compound.
To determine the molar mass of a specific organic compound, you would need the experimental data for the freezing point depression or boiling point elevation and the constants (Kf or Kb) of the specific solvent used.
Without this experimental data, it is not possible to determine the molar mass of the organic compound accurately.
