As2O3
SO3
Since the atomic mass of sulfur is very close to twice the atomic mass of oxygen, the ratio of numbers of oxygen atoms to numbers of oxygen atoms is close to 43:28.5. The closest ratio of small integers is 3:2; therefore the empirical formula is S2O3.
We can't tell. What's the other 90 percent? If you meant 40/60 instead... the mass of sulfur is twice that of oxygen, so a mass ratio of 40:60 is equivalent to an atom ratio of 1:3. The empirical formula would be SO3.
C3h4o2
No, Compounds with the same empirical formula have the same elements in the same ratio. SO2 and CO2 contain different elements. SO2 is a compound of sulfur and oxygen while CO2 is a compound of carbon and oxygen.
