Answer 2

1 mole of a substance has particles equal to Avogadro's number.

• Avogadro's number is 6.022*10²³.
• Now, one mole of any substance contains a particle equal to Avogadro's number. These particles are specific to the substance being talked about.
• The particles specified here can be atoms, electrons or molecules of that substance.
• For example, 1 mole of sodium chloride salt contains 6.022*10²³ sodium atoms and 6.022*10²³ chlorine atoms.
