🤓 Based on our data, we think this question is relevant for Professor Shoemaker's class at PSU.
We’re being asked to determine the empirical formula of a hydrocarbon from the combustion diagram above.
Recall that in combustion analysis, a hydrocarbon reacts with excess O2 to form products.
For a compound composed of C ad H the reaction looks like this:
CxHy + O2 (excess) →x CO2 + y H2O
What is the empirical formula of the hydrocarbon?
