Theoretical van't hoff factor for nacl
Webb3 feb. 2024 · A From Figure 13.9, we can estimate the solubilities of NaCl and CaCl 2 to be about 36 g and 60 g, respectively, per 100 g of water at 0°C. The corresponding concentrations in molality are mNaCl = (36 g NaCl 100 g H2O)( 1 molNaCl 58.44g NaCl)(1000 g 1kg) = 6.2 m mCaCl 2 = (60 g CaCl2 100 g H2O)( 1mol CaCl2 110.98 … WebbSolution:The osmolarity of a solution is equal to the molarity times the the van 't Hoff factor (the number of particles produced in solution per formula unit). 1) Molarity of each of the four substances (I kept some guard digits): NaCl ⇒ 3.50 g / 58.443 g/mol = 0.0598874 mol NaHCO3⇒ 2.50 g / 84.0059 g/mol = 0.0297598 mol
