A mixture of CsCl and RbCl is analyzed for the cesium chloride content. When a 1.00 g mixture is dissolved in 84.3 g water, the freezing point of the solution was found to be -0.301 C. Calculate the mass percent of cesium chloride in the mixture.

I know that it's a colligative property problem, so I need to use deltaTf = i*kf*m but I'm really struggling with how to make it work. Thank you!

A mixture consisting of only rubidium chloride (RbCl, 120.92 g/mol) and sodium chloride (NaCl, 58.44 g/mol) weighs 1.0333 g. When the mixture is dissolved in water and an excess of silver nitrate is added, all the chloride ions associated with the original mixture are precipitated as insoluble silver chloride (AgCl, 143.32 g/mol). The mass of the silver chloride is found to be 1.6048 g. Calculate the mass percentage of rubidium chloride in the original mixture.
