Using the chemical reaction equation 2Mg + O2 = 2MgO, calculate the mass of magnesium oxide

Using the chemical reaction equation 2Mg + O2 = 2MgO, calculate the mass of magnesium oxide if 12 g of magnesium reacts with oxygen.

Magnesium is oxidized very intensively by oxygen. The oxidation reaction is described by the following equation:

Mg + ½ O2 = MgO;

During oxidation, one oxygen atom is attached to the magnesium atom. In this case, one molecule of magnesium oxide is synthesized.

Let’s determine the chemical amount of magnesium.

To do this, divide the available weight of magnesium by the weight of 1 mole of this substance.

M Mg = 24 grams / mol; N Mg = 12/24 = 0.5 mol;

During the reaction, the same amount of magnesium oxide will be synthesized.

Let’s determine its weight.

Let’s multiply the amount of the substance by the weight of 1 mole of the substance.

M MgO = 24 + 16 = 40 grams / mol; m MgO = 0.5 x 40 = 20 grams;
