1. A mole signifies a collection of large fix number of particles (ions, atoms, or molecules).
2. Mole can be represented by n and its unit is also mole or moi.
3. Mole is defined as the amount of substances containing the Avogadro's
number in any kind of chemical unit.
4. Atoms, molecules, and ions are very small. It is quite impossible to calculate
their numbers.
5. The number of particles in a mole of any substance is called the Avogadro's number.
6. The mole of a substance has a mass equivalent of 12.000 g of carbon-12.
7. A mole is the amount of substance that contains 6.02 x 1023 particles.
8. The mass of a mole of any substance measured is called its molar mass.
9. The method of determining the number of moles was developed by John Dalton.
10. Molar mass starts with units of grams per mole (g/mol). When calculating molar mass of a chemical compound, it states how many grams are in one mole of that substance. The number of grams in the molar mass of an element is the same as the atomic mass.
