The mole is an important unit used by chemists to measure substances accurately.
Because the atom is so small, a different unit is required to measure out the number of particles in different substances.
For years, the concept of the mole has proved difficult for students of chemistry.
This ebook, through its interactivity, quizzes, clearly laid out examples and questions (with solutions) helps clear up misconceptions which students seem to find when dealing with the mole.
