Solution - Write the Formula to Determine the Molar Mass of a Solute Using Freezing Point Depresssion Method. - HSC Science (Computer Science) 12th Board Exam - Chemistry

Question

Write the formula to determine the molar mass of a solute using freezing point depresssion method.

Solution

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")`

`m=W_2/(M_2*W_1)`

∴ The molar mass of a solute using freezing depression method is givenby,

`triangle T_f=(K_fW_2)/(M_2W_1)`
