We’re being asked to determine the empirical formula of a compound composed of C, H, and O, given the mass percent of C and O.


Recall that the empirical formula is the simplest whole-number ratio formula of a compound


For this problem, we need to do the following steps:

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

Step 2: Determine the lowest whole number ratio of C, and O to get the empirical formula.
