Problem #8: A 2 52 g sample of a compound containing carbon, hydrogen, nitrogen, oxygen, and sulfur was burned in excess oxygen gas to yield 4 36 grams of CO 2 and 0 892 grams of H 2 O as the only carbon and hydrogen products respectively
- [FREE] Combustion analysis of an unknown compound containing only . . .
To determine the empirical formula of the unknown compound containing only carbon and hydrogen from the combustion analysis data, we follow these steps: From the combustion, 1 1385 g of CO₂ is produced From the combustion, 0 5805 g of H₂O is produced The mole ratio is C:H = 0 0258 : 0 0323
- Worked example: Determining an empirical formula from combustion data
In combustion analysis, an organic compound containing some combination of the elements C, H, N, and S is combusted, and the masses of the combustion products are recorded From this information, we can calculate the empirical formula of the original compound
