1.145 Sou ë 5, Asample of phosphorus weighing 0.500 g was ignited to the oxide in a stream of oxygen A1 41 gas. What is the empirical formula of phosphorus oxide if the product has a mass of 1.145 g? What is the molecular formula of phosphorus oxide if the molar mass is approximately 285 g/mol? 6,00 Empirical formula Molecular formula 6 (optional) Ethylene glycol, the main ingredient in antifreeze, contains 38.7% carbon, 9.7% hydrogen, and 51.6% oxygen. Calculate the empirical and molecular formulas for ethylene glycol, given the molar mass is approximately 60 g/mol. Empirical formula Molecular formula 166
