Glycerol is a syrupy liquid often used in cosmetics and soaps. A 3.25L sample of pure glycerol has a mass of 4.10103g. What is the density of glycerol in g/cm3 ? An element has two naturally occurring isotopes. Isotope 1 has a mass of 120.9038amu and a relative abundance of 57.4%. Isotope 2 has a mass of 122.9042amu. Find the atomic mass of this element and then identify it. The foul odor of rancid butter is due largely to butyric acid, a compound containing carbon, hydrogen, and oxygen. Combustion analysis of a 4.30g sample of butyric acid produces 8.59gCO2 and 3.52g H2O.
