0731. Solving a chemistry problem

1. An excess of hydrogen chloride was added to a mixture of pyridine, aniline and chlorobenzene with a total mass of 110 g, resulting in a mixture of two salts with a total mass of 95.2 g. When the same mixture, but with 2 times less mass, was treated with excess bromine water, 33 g of a white precipitate was formed. Calculate the mass fraction of chlorobenzene in the original mixture
