We’re being asked to determine the empirical formula of a compound composed of C and H given the combustion analysis.

Recall that in combustion analysisa compound reacts with excess O2 to form products. For a compound composed only of C and H, the reaction looks like this:

CxHy + O2 (excess)  x CO2y H2O

This means we need to do the following steps:

Step 1: Calculate the moles of C and H in the compound.

Step 2: Determine the lowest whole number ratio of C and H to get the empirical formula. ###### Problem Details
