We’re being asked to determine the empirical formula of a compound given the mass percent of C, H, 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.
An unknown compound was determined to be 74.97% carbon, 8.39% hydrogen, and 16.64% oxygen. Calculate the empirical formula.
