## Main Question or Discussion Point

An unknown alcohol is analyzed by combustion. When a 1.50 gram sample of the compound (containing C, H, and O) is burned, 3.30g of CO2 and 1.80g of H20 are produced. Determine the empirical formula of the compound.

What I did was find the number of grams of Carbon and Hydrogen that are produced by using their respective percents. Then I subtracted those numbers from the total produced to get the number of grams of O in the original. I thought that the LCM(cons. of mass) allowed me to do this, but I don;'t think that it is right--can someone please help me figure out how to do this(BTW, the answer I got was C3H8O)
