4 mol MgO
Explanation:
Let us first look at the equation. As per the equation , 2 moles of Magnesium produces two moles of MgO . If we double the amount of Magnesium , it will also double the amount of MgO we will obtain.
2 Moles of Mg produces 2 moles of MgO
4 Moles of Mg will produce X moles of MgO
2 Mole Mg / 4 Mole Mg = 2 moles of MgO/ X moles of MgO
1/ 2 = 2/X
1.X = 2.2
X = 4
