Eugenol is the active ingredient in the oil of cloves used to relieve toothache. Calculate the boiling point of a solution in which 0.17 grams of eugenol, (C10H12, O2) is dissolved in 10.0 grams of benzene. (Kb benzene= 2.53 0C/m; Tb(solvent) = 80.10 0C)

I dont get it

DrBob222 · Answer

mols eugenol = grams/molar mass = ?
molality eugenol = mols from above/kg solvent and kg solvent = 0.01
Solve for molality.
Then delta T = Kb*molality
delta T = Kb*m. YOu know Kb and m. solve for delta T, then add that to 80.1 to find the boiling point of the solution.
Post your work if you get stuck.
