Question

If there is an insufficient amount of oxygen, you can get incomplete combustion. If this occurred while analyzing the unknown samples from parts a, b, and c, describe what errors would occur while trying to determine the empirical formula.

***Please do NOT solve parts a,b,c!! I ONLY need help with the question above***

part a: A 10.00g unknown sample with a formula of CxH_Y was analyzed by combustion analysis. The sample produced 27.42g of CO2(g) and 22.46g H₂O(g). Find the empirical formula of the unknown sample.

for part a I determined the empirical formula to be: CH4

part b: A 10.00 gram unknown sample containing C, H, O, was analyzed by combustion analysis. The sample produced 19.10 grams of CO2 and 11.73 grams of H2O. Find the empirical formula of the unknown sample.

for part b I determined the empirical formula to be: C2H6O

part c: A 15.00 gram unknown sample containing C, H, O was analyzed by combustion analysis. The sample produced 29.3 grams of CO2 and 20.8 grams of H2O. Find the empirical formula of the unknown.

for part c I determined the empirical formula to be: C2H8O

Once again, I do NOT need help with a, b, or c. I need help answering the question at the very top of the page.

Thanks
