Question

What is the relation between a mole and a molecule?

Answer 1

• A mole of a substance is referred to as the mass of the substance containing the same number of fundamental units as atoms in exactly 12.000 g of carbon-12.
• These may be electrons, protons, neutrons, atoms, ions, etc.
• The following formula can represent the number of moles of a substance in a given pure sample
• n=$\mathrm{N}/{\mathrm{N}}_{\mathrm{A}}$ where n is the number of moles of the substance.
• ${\mathrm{N}}_{\mathrm{A}}$ is the Avogadro constant.
• Hence A mole represents 6.022 x ${10}^{23}$molecules.
