Question
How much water is produced when 26gm of benzene is burnt?
- 18 gm
- 76 gm
- 26 gm
- 54 gm
Hint:
1 mole benzene burns to give 3 moles of water.
The correct answer is: 18 gm
C6H6 + 15/2O2 
6CO2 + 3H2O
1 mole benzene burns to give 3 moles of water.
78g benzene gives 54g of water.
26g of benzene gives 18g of water.
