How much magnesium oxide is formed as a result of the reaction of magnesium with oxygen if 0.4 mol

How much magnesium oxide is formed as a result of the reaction of magnesium with oxygen if 0.4 mol of magnesium has entered the reaction?

Let’s write the formula:
2Mg + O2 = 2MgO
From the formula we find the ratio of the amount of MgO and MgO:
2 mol – 2 mol
By condition, we have 0.4 mol of MgO, which means that the amount of MgO is 0.4 mol.
