Delta T = 1000 *Kf * w/m* 500
0.74 = 1000* 1.86* 20/m*500
on solving
m = 100
Actual molar mass = 100
Hencce degree of ionisation = 0%

Dear Student,
Please find below the solution to your problem.

Delta T = 1000 *Kf * w/m* 500
0.74 = 1000* 1.86* 20/m*500
on solving
m = 100
Actual molar mass = 100
Hencce degree of ionisation = 0%

Thanks and Regards
