Package directions call for 2 tsp salt in 4 qt water
4 qt water ≅ 3.79 L = 3.79 kg
2 tsp salt ≅ 11.84 g ≅ 0.2 mol Boiling point elevation: ΔT = iKbm
ΔT = change in temperature (℃)
i = dissociation constant = 2 Kb = boiling point elevation constant = 0.512 ℃/m
m = molality of solute (mol solute / kg solvent) 0.2 mol NaCl / 3.79 kg H2O = 0.05 ΔT = 2 * 0.512 * 0.05 = 0.05 ℃
