Units of Measurement
- The unit of measurement used for amount of substance is the mole (mol).
Mole and Avogadro's Number
- One mole contains as many particles (atoms, molecules, ions, or electrons) as there are atoms in 0.012 kilogram of carbon-12.
- The Avogadro number is a fundamental constant that represents the number of particles in one mole of a substance.
- The Avogadro number is 6.02214076 × 10^23 particles.
- The numerical value of the Avogadro constant is 6.02214076 × 10^23 mol^-1.
Applications of Mole
- The mole is widely used for quantifying the amount of substance in chemistry, physics, and biology.
- It is used to express the amount of reactants and products in a chemical reaction.
- It is also used to calculate the concentration of solutions and the quantity of substances in a mixture.
