It's Au (gold ). The atomic mass of oxygen is 15.9994 u, and one gram has 1 g / 15.9994 u = 3.7640 * 10^22 oxygen atoms. ( 1 u = 1.66054 * 10 ^-24 g ) There are 2/3 as many---2.5093*10^22--- atoms belonging to the other element. Divide 8.2073 g by that, convert to atomic mass units. You should have 196.97 u. According to the CRC Handbook of Chemistry and Physics, the atomic mass of Au is 196.96655.
