How do concentrations of similar products compare with one another? In this topic, you learned how to calculate the concentration of solutions by molarity, molality, percent by mass, and percent by volume. The next time you are shopping, make sure to check the concentration of the “active” ingredient. This will help you determine how many grams of active ingredient you are actually getting.
