When 2.40 moles of tricarbon octahydride are combusted, how many grams of water and carbon dioxide are formed?
Sam and Bob are conducting an investigation to determine the empirical formula of iron oxide. They start with an 85.65g piece of iron metal and burn it in air. The mass of the iron oxide produced is 118.37g. Sam thinks the empirical formula of iron oxide is Fe3O4 and Bob thinks it is FeO. Use what you know about how to determine the empirical formula of a compound.
