[8], Carbon tetrachloride is one of the most potent hepatotoxins (toxic to the liver), so much so that it is widely used in scientific research to evaluate hepatoprotective agents. Doing these problems is almost nothing more than division if you understand what the problem is asking. The empirical formula is the simplest formula of a compound. Typically, we interrogate the empirical formula by experimental means (and that is what "empirical" means, "by experiment"), usually combustion analysis, to give the percentage by mass of, carbon, hydrogen, and nitrogen, and by a Mohr titration to give halide content. K 3 Fe(CN) 6 is 35.62% potassium, 16.96% iron, 21.88% carbon and 25.53% nitrogen.
