Determine boiling point of compounds
WebThe Formula for Boiling Point. It are often calculated as: Kb = RTb2M/ΔHv, R is that the universal gas constant. Tb is that the boiling temperature of the pure solvent [in K] M is that the molar mass of the solvent. ΔHv is that the heat of vaporization per mole of the solvent. If the warmth of vaporization and therefore the vapor pressure of ...
