A compound containing carbon and nitrogen has a composition of 46.16% carbon and 53.84% nitrogen by mass.A solution prepared by dissolving 3.912 g of this compound in 20.00 g of carbon tetrachloride,CCl₄,produces a solution that boils at 95.63°C.What is the molecular formula of the compound? (K_b for CCl₄ is 5.03°C/m,and pure CCl₄ has a freezing point of 76.72°C.) A)C₂N₂ B)CN₂ C)C₃N₃ D)CN E)C₂N₄

Question

Quizplus · Accepted Answer

The correct answer is A because the molecular formula of the compound is C2N2. This can be determined by calculating the empirical formula of the compound, which is CN, and then multiplying the empirical formula by a whole number to get the molecular formula. In this case, the molecular formula is C2N2 because the empirical formula is multiplied by 2.
