- A “mole” is approximately 6.022 × 1023 atoms or molecules.
- The unit of mole is ‘mol’.
- A mol is not a measure of “weight” – rather, it is a measure of “number”.
- Using the periodic table, it is easy to calculate the molar weight of atoms and molecules. Knowing the element number of the atoms in a molecule, you will be able to do a rough estimate of the molar weight of a substance.
Learning Outcomes
After completing this module, you should be able to:
- understand what a ‘mole’ is and what it measures
- understand the information available from a periodic table and use it to calculate the weight of 1 mole of any given chemical compound
