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.

What is the molecular formula of fructose with C 40 percent H 6.72 percent O 53.28 percent?
We assume 100 grams and turn those percentages into grams and find moles of species. 40 grams carbon (1 mole C/12.01 grams) = 3.33 moles C 6.72 grams hydrogen (1 mole H/1.008 grams) = 6.67 moles H 53.28 grams oxygen (1 mole O/16 grams) = 3.33 The smallest mole number is 1, so we have two small numbers. Divide the large number by the small. 6.67/3/33 = 2 so.............. CH2O is the empirical formula. You did not state that you had a quantity of this compound ( such as 60 grams, or whatever ), so the molecular formula can not be found from this info. C6H12O6 is of course the molecular formula. To find the molecular formula you need a mass of the compound aside from the simple percentages. Then you find, as we have done, the empirical formula. you divide the mass given by the mass of the empirical formula and then take that quotient and multiply it times the empirical formula. In this case (CH2O) * 6 = C6H12O6, the molecular formula
What is the empirical formula for 52.5 percent oxygen 25.4 percent phosphorus 22.1 percent aluminum?
Well first we assume a 100 g sample and then convert the elements into moles. We then divide them all by the number of moles that is the lowest of the 3. This procedure gives us AlPO4

75.7 percent arsenic and 24.3 percent oxygen what empirical formula would it have?
As2O3
What is the empirical formula of a compound that is 40percent sulfur and 60percent oxygen by weight?
SO3
What is the empirical formula of a compound that contains 57 percent sulfur and 43 percent oxygen by mass?
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.
What is the empirical formula for 50.0 percent carbon 6.00 percent hydrogen 44.0 percent oxygen?
C3h4o2
Does CO2 and SO2 have the same empirical formula?
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.
