1.98 moles of Magnesium oxide were formed.
The balanced chemical equation is the equation in which the number of atoms on the reactant side is equal to the number of atoms on the product side in an equation.
Now write the balanced chemical equation
2Mg + O₂ → 2MgO
(2 × 24) 2 × (24 + 16)
48 g of Mg gives 80 g of MgO
To find the number of moles use the expression
Number of moles = [tex]\frac{\text{Given mass}}{\text{Molar mass}}[/tex]
= [tex]\frac{80}{40.3}[/tex]
= 1.98 mole
Thus from the above conclusion we can say that 1.98 moles of Magnesium oxide were formed.
