2.49g of Mg will produce 4.13g of MgO

Step-by-step explanation:

2Mg(s) + O2(g) → 2MgO(s) + energy

Molecular weight of Mg = 24.305 g/mol

Molecular mass of MgO = 40.3044 g/mol

According to the question,

2 X 24.305g of Mg will produce 2 X 40.3044 g of MgO

2.490 g of Mg will produce =
(40.3044)/(24.305) X 2.490 g of MgO

= 4.13g of MgO

Therefore, 2.49g of Mg will produce 4.13g of MgO
