linuspauling Here are the steps for solving an empirical formula problem: 1) Write the equation (if not given), so you think through the reaction. For ex., combustion of a compound made of C, H, and N. (Reacts with O2, produces CO2 and H2O, so you can determine C from amount of CO2 produced and H from H2O). So, CxHyNz + O2 yields CO2 + H2O 2) Find the g of C and H. Given 0.1638 g of CO2 were produced from 0.1156 g CxHyNz, find the g of C in compound: Given mass of CO2 x Mass of C / Mass of CO2 = 0.1638 g x 12.01 g/mol /44.01 g/mol = 0.04470 g C Find the g of H similarly. 3) Find the %C and %H in the original compound: 0.04470 g C / 0.1156 g CxHyNz x 100% = 38.67% C. Find the %H using the same method (16.22% H) 4) Find the %N in the compound. Assume 100 g and back calculate (100.00 g CxHyNz – 38.67 g C – 16.22 g H = g N). 5) Convert all masses to mol of the substance (ex. 38.67 g C/12.01 g/mol = 3.22 mol) 6) Divide all masses by the lowest # of mols. Round to whole numbers if close or multiply by a factor to get whole numbers. These are your subscripts (# of atoms for each), so write your formula. 2nd Qtr.
