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.
Step-by-step 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.
