Determine the boiling point of a sol'n containing 96.8 g MgBr2 in 2014 g of water.

Answer 1

delta T = i*Kb*m
delta T is what you want.
i for MgBr2 is the van't Hoff factor = 3.
Kb you can look it up. It't approx 0.5
m = mols/kg solvent. You have g water. Convert to Kg.
Then mols MgBr2 = grams/molar mas.
