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.
