Formula for calculating boiling point
WebThe boiling point elevation is calculated by the following formula: Δ T b = m x K b The moles of particles from 5.40 g FeCl 3 are calculated by multiplying the moles of FeCl 3 … WebBoiling point elevation is the raising of a solvent's boiling point due to the addition of a solute. Similarly, freezing point depression is the lowering of a solvent's freezing point due to the addition of a solute. In fact, as the boiling point of a solvent increases, its freezing point decreases. An example of this would be the addition of ...
