JILLIAN, Alan. We prefer to keep the same screen name. Refer to your other problem. It a little simpler with just CxHy. This one is CxHyOz. The only difference is this.
Convert 12.53 g CO2 to g C.
Convert 3.849 g H2O to g H.
To find g O, it is
g O = 8.408 g - g C - g H
Then convert g C to mols C, g H to mols H, and g O to mols O.
Then convert these to ratios of whole numbers the same was as the other problem. The molecular formula is done the same way, also.
A 8.408 gram sample of an organic compound containing C, H and O is analyzed by combustion analysis and 12.53 grams of CO2 and 3.849 grams of H2O are produced.
In a separate experiment, the molar mass is found to be 118.1 g/mol. Determine the empirical formula and the molecular formula of the organic compound.
Find empirical formula and molecular formula.
Put in order of C,H,O.

i literally have no idea how to do these and your explanations are not helping..... like i have no example and i need you to work one out and i can do the other but they are do soon and i have no clue what you are saying.
See my response to your earlier CxHy question below. I've worked it in detail. I hope things work out for you very well.
