Conceptual Challenge Problems

These rigorous, thought-provoking problems integrate conceptual learning with problem solving and are suitable for group work.

CP3.A (Section 3.9) A chemist analyzes three compounds and reports these data for the percent by mass of the elements Ex, Ey, and Ez in each compound.

Assume that you accept the notion that the numbers of atoms of the elements in compounds are in small whole-number ratios and that the number of atoms in a sample of any element is directly proportional to that sample’s mass. What is possible for you to know about the empirical formulas for these three compounds?
