Question
How much CO2 will be produced when 1 mole of pentane is burnt?
- 110 gm
- 220 gm
- 230 gm
- 240 gm
Hint:
When 1 mole pentane is burnt it gives 5 moles of carbon dioxide.
The correct answer is: 220 gm
C5H12 + 8O2 
5CO2 + 6H2O
When 1 mole pentane is burnt it gives 5 moles of carbon dioxide.
5 moles of carbon dioxide means 220g.
