1. The van't hoff factor for CaCL2 is 2.71. What is its mass % in aqueous solution that has Tf = -1.14°C
So I think I am suppose to use the change in freezing point equation: ΔTf= kfmi. Where kf = is the molal freezing point depression constant, i = van't hoff factor, m = molal concentration.
Other than that, I am kind of lost. It seems like there is not enough variables given. Any suggestions?
