I assume this is a beginning chemistry course and this is a problem on colligative properties. However it isn't a very good problem because ethanol is NOT a non-volatile solute and the property we are discussing does not work for volatile solutes.. I suppose for this problem we must assume it is a non-volatile solute..
mols ethanol = grams/molar mass
molality = mols/kg solvent
delta T = Kb*m, solve for delta T and add to the normal boiling point of water which is 100 C.
25g of ethanol is dissolved in 1.50 kg of whater. what will the boiling point of the solution be?
