Mixture- identity of metals
Not what you're looking for?
When 8.900 g of a mixture of an alkali metal chloride (XCl) and an alkaline earth chloride (YCl2) was dissolved in 150.0g of water, the freezing point of the resultant solution was -4.42C. Addition of an excess of aqueous AGNO3 to the solution yielded a white precipitate with a mass of 27.575 g (This white precipitate would be AgCl). How much of each metal chloride was present in the original mixture, and what are the identities of the two metals, X and Y?
