Empirical Formula from Stoichiometry!? 1. The problem statement, all variables and given/known data More than 1 billion pounds of adipic acid (MW 146.1 g/mol) is manufactured in the US each year. Most of it is used to make synthetic fabrics. Adipic acid contains only C, H, and O. Combustion of a 1.6380g sample of adipic acid gives 2.960g of CO2 and 1.010 g of H2O. What is the simplest formula for adipic acid? What is its molecular formula? 2. Relevant equations (Adipic Acid) + O2 -> CO2 + H2O 3. The attempt at a solution Convert to .0561 mol H2O Convert to .0673 mol Co2 Convert to .0112 mol adipic acid using stoichiometry (I understand this part).
