  • Avogadro's number, or constant, is the number to which the mass of an atom must be multiplied to give a mass in grams numerically equal to its relative atomic mass. That sounds like a mouthful, but it just means that an Avogadro number of carbon atoms has a mass of 12g, because the relative mass of carbon = 12. •When put in general terms, this becomes Avogadro's Principle (or Avogadro's Hypothesis): Equal volumes of gases at the same temperature and pressure contain the same number of gas molecules. Avogadro's Principle (Avogadro's Hypothesis) is extremely useful when we need to know the amount or volume of gas at constant temperature and pressure.
