Suppose that a 6.0g mixture of naphthalene(C10H8) and anthracene(C14H10) is dissolved in 300g of benzene. When the solution is cooled, it begins to freeze at a temp that is 0.70*C below the normal freezing point(5.5*C) of pure benzene. Find the number of grams of naphthalene and grams of anthracene in the original mixture.
