ΔTb = Kb × m × iΔTf = Kf × m × iπ = iMRTP_solution = P° × χ_solventAlways calculate molality (moles of solute per kg of solvent) first. Then apply the formula with the van't Hoff factor i (i = 1 for non-electrolytes, > 1 for electrolytes). Osmotic pressure: π = iMRT requires molarity, not molality.
