<h2>Let us solve for it </h2>
Explanation:
Magnesium oxide
- It is MgO
- Its molecular mass is : 24 +16=40 g
- When MgO decomposes it forms = 3.54 g of oxygen gas
- when 40 g of MgO decomposes it forms = 16g of oxygen
- or we can say that :
- 16g of oxygen is produced when 40 g of MgO is decomposed .
- 1g of oxygen will be formed from =40/16g of MgO
- 3.54 g of oxygen will be formed = 40/16 x 3.54 =8.85g of MgO
