2Mg + O2 = 2MgO. Magnesium is the limiting reactant if 2.5g of magnesium is reacted how much magnesium oxide is made?

The answer for the following problem is mentioned below.

Therefore; if 2.5g of magnesium is reacted then 4.16 grams of magnesium oxide is reacted.

Explanation:

Given:

mass of magnesium = 2.5 grams

We know;

molar mass of magnesium (Mg) = 24 grams

molar mass of magnesium oxide (MgO) = 24 + 16 = 40 grams

2Mg + O2 → 2MgO

2*24 2*40

If;

2*24 grams of Mg → 2*40 grams of MgO

Then;

2.5 grams of Mg →?

= (2*40 * 2.5) : 2*24

= 4.16 grams

Therefore; if 2.5g of magnesium is reacted then 4.16 grams of magnesium oxide is reacted.

So therefore 4.16 grams of magnesium oxide is made.
