Imagine two solutions with the same concentration and the sameboiling point, but one has ethanol as the solvent and the other hascarbon tetrachloride as the solvent. Determine that molalconcentration, m (or b),m (or b), and boiling point, Tb.Tb.
| Solvent | Normal boiling point (∘C)(∘C) | Kb (∘C/m)Kb (∘C/m) |
|---|
| ethanol | 78.4 | 1.22 |
| carbon tetrachloride | 76.8 | 5.03 |
