Calculate the boiling point of a 13.50 𝑚 aqueous solution of ethylene glycol.

Answer 1

∆T = imK

∆T = change in boiling point = ?

i = van't Hoff factor = 1 for ethylene glycol which is a non electrolyte

m = molality = 13.50

K = boiling point constant for water = 0.512 º/m

Solving for ∆T

∆T = (1)(13.50)(0.512)

∆T = 6.912º

Boiling point of solution = 100º + 6.912º = 106.9º
