Downloading the PDF is only the first step. To actually improve your test scores, follow this three-step study protocol:

: Familiarize yourself with terms like molarity, molality, and how to prepare solutions of specific concentrations.

One of the first steps in many chemistry calculations is determining the molar mass of a compound. The molar mass is the mass of one mole of that substance, expressed in grams per mole (g/mol).

Using the concept that 1 mole of any gas occupies 24 $dm^3$ at room temperature and pressure (RTP), the PDF provides practice problems for calculating gas volumes from reaction masses.
