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,

b. accuracy of the data matters alot more than its number of digits, organization or amount of detail. quantitative observation is more accepted than the qualitative observation.
