Mole Practice Name: 23 Avogadro's Number (6.02 x 10 ) was not discovered by him, but named in honor of him. It was Dr. Avogadro's original hypothesis about the volume of gas molecules that led to the development of the mole concept many years later. Use your newfound molar repertoire to complete the following Date.
What is the molecular formula? (C2H4O2) Aniline, a starting material for urethane plastic foams, consists of C, H, and N. Combustion of such compounds yields CO2, H2O, and N2 as products. If the combustion of 9.71 g of aniline yields 6.63 g H2O and 1.46 g N2, what is its empirical formula?
