Calculate the freezing point of a 2.00 molal solution of the nonelectrolyte glucose. the freezing point constant for water is 1.86 °c/molal.

Answer : The freezing point of the solution is,

Explanation :  Given,

Molality of the solution = 2.00 m

Formula used :  

where,

= change in freezing point

= temperature of pure water =

= temperature of solution = ?

i = Van't Hoff factor for non-electrolyte solution = 1

= freezing point constant =

m = molality  = 2.00 m

Now put all the given values in this formula, we get:

Therefore, the freezing point of the solution is,
