Presentation Transcript

  1. What is a Mole? A mole of a substance is 6.02 x 1023 representative particles of that substance. • The number of particles in a mole (6.02 x 1023) is called Avogadro’s number.

  2. The Mass of a Mole of an Element The mass of a mole of an element is its molar mass.

  3. The Mole-Volume Relationship At STP 1 mol, or 6.02 x 1023 representative particles, of any gas occupies a volume of 22.4 L. Standard temperature and pressure (STP) means a temperature of 0C and a pressure of 1 atmosphere.

  4. The Mole Road Map

  5. The Percent Composition of a Compound

  6. Empirical Formulas The empirical formula of a compound gives the lowest whole-number mole ratio of the atoms of the elements in a compound.

  7. Molecular Formulas The molecular formula of a compound is either the same as its experimentally determined empirical formula, or it is a simple whole-number multiple of its empirical formula.
