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 mass and moles of C, H, and O in the compound.
Step 2: Determine the lowest whole number ratio of C, H, and O to get the empirical formula.
Determine the empirical formula for a compound that contains C, H, and O. It contains 52.14% C and 34.73% O by mass.
