Chapter 7: The Mole and Its Applications

Atoms have a specific mass value that varies from element to element. Knowing the mass values of elements allows one to determine the amount of atoms or molecules in a sample. In Chapter 7, we introduce the concept of the mole and demonstrate its usefulness in relating mass to the number of particles.
