This test assesses students' ability not only to do basic mole calculations such as mole-mass or mole-formula units questions but also forces students to correctly form ionic compounds. The number of cubic decimeters of any gas at STP is also used. Students are required to know how to form empirical formulas from the amounts of given elements in a compound. The test also assesses students' ability to find the molar mass of a hydrate.
Lastly, the bonus problem is an introduction to stoichiometry.
