Notes: Concentration (Molarity)

• For example, the freezing pt of water is lowered by 1.86°C with the addition of any molecular solute at a concentration of 1 m. • However, a 1 m NaCl solution contains 2 molal conc. of IONS. Thus, the freezing pt depression for NaCl is 3.72°C…double that of a molecular solute. ................
