When heated, lithium reacts with nitrogen to form lithium nitride: 6li(s) + n2(g) → 2li3n(s). a) what is the theoretical yield of li3n in grams when 12.3 g of li is heated with 33.6 g of n2? b) if the actual yield of li3n is 5.45 g, what is the percent yield of the reaction?

Determine the empirical formula of a compound containing 40.6 grams of carbon, 5.1 grams of hydrogen, and 54.2 grams of oxygen. in an experiment, the molar mass of the compound was determined to be 118.084 g/mol. what is the molecular formula of the compound? for both questions, show your work or explain how you determined the formulas by giving specific values used in calculations.
