This module is critical because it introduces the mole, the central units of chemistry. The mole is used to determine the molar mass (molecular weight) of molecules, and the concentration of solutes in solutions. This material is covered in Chapter 3 of Flowers et al.,. This module requires a great deal of mathematical problem solving of word problems and we'll spend a good deal of time understanding how to develop strategies for different types of problems. Warm up your calculators and have a periodic table with you too.
