Answer:
7.2 moles
Explanation:
Given the equation:
C2H6 + O2 → CO2 + H2O
First step is to balance the equation:
For complete combustion of ethane :
2C2H6 + 7O2 → 4CO2 + 6H2O
From the equation above, Mole ratio of ethane to CO2 ;
2C2H6 : 4CO2
2 : 4, reducing to lowest term; 1 : 2
Thus ;
1 mole C2H6 - - - - > 2 moles CO2
Therefore when ;
3.6 moles C2H6 - - - - > x moles CO2
x - - - - > (2 × 3.6) moles
x - - - > 7.2 moles
Therefore,
3.6 moles C2H6 = 7.2 moles CO2
This is a very hard question. I had hard times solving it. The answer is right.
