Quizplus · Accepted Answer

The van't Hoff factor (i) can be calculated using the formula for freezing point depression: ΔTf = i * Kf * m, where ΔTf is the change in freezing point, Kf is the freezing point depression constant, and m is the molality of the solution. Given ΔTf = 0.43°C, Kf = 1.86°C/m, and m = 0.100 m, we can rearrange the formula to solve for i: i = ΔTf / (Kf * m) = 0.43°C / (1.86°C/m * 0.100 m) = 2.3.
