Answer:
11.1 moles
Explanation:
Given data:
Mass of ethane = 5.55 mol
Number of moles of COâ‚‚ produced = ?
Solution:
Chemical equation:
2C₂H₆ + 7O₂    →   4CO₂ + 6H₂O
Now we will compare the moles of ethane and carbondioxide.
       C₂H₆      :      CO₂
         2       :       4
        5.55      :     4/2×5.55 = 11.1 moles
Number of moles of COâ‚‚ produced are 11.1 moles.
