Homework Statement
Calculate the boiling point (in degrees C) of a solution made by dissolving 7.49 g of urea {CO(NH2)2} in 28.0 g of water. The Kbp of the solvent is 0.512 K/m and the normal boiling point is 373 K
Homework Equations
Delta Tf = (i)(m)(Kbp)
The Attempt at a Solution
Kbp= 0.512 k/m
molality (m)= ?
first I have to find molality
(7.49g/60g)/(.028 kg water) = 4.458m
I don't know what the i value is. What do I do with the normal boiling point?
The answer is 102.283 celicus this would be 375.28K.
Then I did some research on the internet I came across this site that didn't use the i value is this possible.
375.28= 373 + delta Tf
