The chemical formula for oxygen is O2 and for individual oxygen  atom its symbol is O.   Gases such as oxygen exist as diatomic molecules.
EFW â 32+32+38 = 102 g. the empirical formula is also the molecular formula. Problem #4: Ammonia reacts with phosphoric acid to form a compound that contains 28.2% nitrogen, 20.8% phosphorous, 8.1% hydrogen and 42.9% oxygen. Calculate the empirical formula of this compound.) Use the scaling factor computed just above to determine the molecular formula: SO 2 times 1 gives SO 2 for the molecular formula. Problem #2: A compound is found to contain 64.80 % carbon, 13.62 % hydrogen, and 21.58 % oxygen by weight.
