We’re being asked to determine the empirical formula of aspirin 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.
Aspirin has the following mass percent composition: C 60.00%, H 4.48%, and O 35.52%. Its empirical formula is:
