Problem: The koala dines exclusively on eucalyptus leaves. Its digestive system detoxifies the eucalyptus oil, a poison to other animals. The chief constituent in eucalyptus oil is a substance called eucalyptol, which contains 77.87% C, 11.76% H, and the remainder O.What is the empirical formula for this substance?

FREE Expert Solution

We’re being asked to determine the empirical formula of eucalyptol, 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.
