. When 3 g of carbon is burnt in 8 g of oxygen
11.00 g of carbon dioxide (CO2) is produced. What mass of CO2 will be formed when 3.00 g of carbon is burnt in 50.0 g of oxygen?
Best Answer
Ans: C + O2 ---------CO2
3 g of carbon + 8 g of oxygen = 11 g of CO2
3 g of carbon will react with only 8.0 g of oxygen to form 11 g of CO2
50 – 8 = 42 g of O2 will remain unreacted.
Law of definite proportion will govern this answer
