we make a solution of water and ethylene glycol c2h4(oh)2 which contains 24 g of the glycol for each 74 g of water. What is the boiling point of ethylene?

Answer 1

#1. You need to find the caps key and use it.
2. You need to proof you post. "What is the boiling point of ethylene---I assume you meane ethylene glycol".

mols ethylene glycol = grams/molar mass = ?
kg solve is 0.074 kg
delta T = Kb*m with Kb approx 0.5 but that an estimate.
Then add delta T to the normal boiling point of H2O to find the new boiling point.
