2.2: Avogadro's Number and Moles

• Stephen Lower's "General Chemistry Virtual Textbook: Avogadro's Number and the Mole"

  Read this webpage. This material covers moles and molar masses, which will be a recurring theme in later units. Keep in mind that the "mole" is nothing more than a number. Just as a dozen always equals 12 and a gross is always 144, a mole always equals 6.022 x 10²³.
