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 = [tex]3.01 \times 10^{22 }[/tex]
1 mole of a substance = [tex]6.022 \times 10^{22 }[/tex]
Now, calculating the moles of magnesium in the given entity:
Mole = [tex]3.01 \times 10^{22}\times \dfrac{1 \text {mol}}{6.022 \times 10 ^{22}}[/tex]
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 ([tex]6.022 \times 10^{22 }[/tex]).
Therefore, the mole in [tex]3.01 \times 10^{22 }[/tex] atoms of Magnesium will be 0.05.
