WebJul 1, 2024 · Step 1: Calculate the molality of the NaCl molality (m) of NaCl = moles of NaCl/kg water From the periodic table, find the atomic masses of the elements: atomic mass Na = 22.99 atomic mass Cl = 35.45 moles of … WebThis is consistent with the freezing point depression formula, as Mg has less mass than Ca. Beyond 24%, CaCl2 is superior. This is because the eutectic point of MgCl2-water is at 21.6 percent, whereas the eutectic point of CaCl2-water is at 30%. The freezing point depression formula is only valid at reasonably low concentrations.
