WebFeb 22, 2024 · For the purpose of freezing point depression, we would go with the 2.0mol of ions when we calculate the molality of the solution. In this question, all of the solutions have water as a solvent, which means that we can disregard the K f value and instead concentrate upon the molality of solute particles of the solution. We can get that by first ... WebAug 25, 2024 · In reality, this is not always the case. Instead, the observed change in freezing points for 0.10 m aqueous solutions of \(NaCl\) and KCl are significantly less than expected (−0.348°C and −0.344°C, respectively, rather than −0.372°C), which suggests that fewer particles than we expected are present in solution. ...
