Moles are the base unit of atoms, molecules, ions, or any other substance. It is exactly 6.022 × 10²³ entities of any substance. The mole is equal to the ratio of the given mass to the molar mass.
Given that:
Magnesium atoms =
1 mole of a substance =
Now, calculating the moles of magnesium in the given entity:
Mole =
Mole = 0.05 moles.
Thus, the moles are defined as the base unit of any substance. It was discovered by the scientist Avogadro and is also known as Avogadro's number ().
Therefore, the mole in atoms of Magnesium will be 0.05.
