Ethylene glycol, c2h6o2, a nonelectrolyte, is added to the water in a radiator to give a solution containing 0.75 mole of ethylene glycol in 1 kg of water (solvent). what is the boiling point of the solution?

Answer : The boiling point of the solution is

Explanation :

Formula used for Elevation in boiling point :

or,

where,

= boiling point of solution = ?

= boiling point of water =

= boiling point constant  of water =

m = molality

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

= moles of solute (ethylene glycol) = 0.75 mole

= mass of solvent (water) = 1 kg

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

Therefore, the boiling point of the solution is
