Avogadro's number (Equation 1.4.2 1.4.2) like any pure number, is dimensionless. However, it also defines the mole, so we can also express NA as 6.02 × 1023 mol–1; in this form, it is properly known as Avogadro's constant. This construction emphasizes the role of Avogadro's number as a conversion factor between number of moles and number of ...Moles of Chalk Lab Unit 5 - Nomenclature and Formula Stoichiometry Big Ideas- Core Concepts: Elements from compounds in predictable ratios can be named systematically.
