Write the formula to determine the molar mass of a solute using freezing point depresssion method.
Depression of freezing point and molar mass of the solute:
When W2 gram of solute with molar mass M2 is dissolved in W1 gram of solvent, the molality m is given by
`m="Mass of solute in kg"/("Molar mass of solue in kg "×" Mass of solvent in kg")`
∴ The molar mass of a solute using freezing depression method is givenby,
