Question

A solution of urea in h2o has a boiling point of 100.18 c calculate the freezing point of solution

Answer 1

Actual Boiling pt. = 100℃

Given boiling pt. = 100.18℃

Now we need to find error

Error = measured boiling pt. - Actual boiling pt.

Error = 100.18 - 100= 0.18

So freezing point is given by

Error = measured freezing pt. - Actual freezing pt.

0.18 = measured freezing pt. - 0

So freezing point would be 0.18℃.
