One kg of carbon monoxide requires how much quantity of oxygen to produce 11/7 kg of carbon dioxide gas?
- A. 4/7 kg
- B. 11/4 kg
- C. 9/7 kg
- D. None of the above
Answer: A. 4/7 kg
Explanation: CO + 0.5 O2 -> CO2. 1/2 mole of O2 would make 1 mole CO2. So, 16 kg O2 would make 44 kg CO2. Then (16/44) kg O2 would make 1 kg CO2. Therefore, 11/7 kg CO2 is made by (11/7) * (16/44) kg O2 = 4/7 kg O2.
