A weighed sample of iron (Fe) is added to liquid bromine (Br2) and allowed to react completely. The reaction produces a single product, which can be isolated and weighed. The experiment was repeated a number of times with different masses of iron but with the same mass of bromine (see graph below). (a) What mass of Br2 is used when the reaction consumes 2.0 g of Fe? (b) What is the mole ratio of Br2 to Fe in the reaction? (c) What is the empirical formula of the product? (d) Write the balanced chemical equation tor the reaction of iron and bromine. (e) What is the name of the reaction product? (f) Which statement or statements best describe the experiments summarized by the graph? (i) When 1.00 g of Fe is added to the Br2, Fe is the limiting reagent. (ii) When 3.50 g of Fe is added to the Br2, there is an excess of Br2. (iii) When 2.50 g of Fe is added to the Br2, both reactanu are used up compietely. (iv) When 2.00 g of Fe is added to the Br2, 10.8 g of product is formed. The percent yield must therefore be 20.0%.

A compound containing only C, H, and O, was extracted from the bark of the sassafras tree. The combustion of 47.3 mg produced 128 mg of CO2and 26.3 mg of H2O. The molar mass of the compound was 162 g/mol. Determine its empirical and molecular formulas. I am really just not sure how to start this problem. I know how I would do this if I were given percentages of material but since the starting material is less mass than the produced materials I am not sure how to account for the oxygen that must have gone into the products. I know I need to find how number ratios of moles so would I just turn the CO2 and H2O into moles and then compare to the molar mass? help!!
