Answer 1

Answer:

3.5 moles CO

Explanation:

To convert between moles of CO and moles of C₂H₆, you need to use the mole-to-mole ratio. These values are the coefficients in the reaction. Because you are starting with C₂H₆, the coefficient of C₂H₆ should be on the bottom of the ratio to allow for the cancellation of units.

2 C₂H₆ + 5 O₂  ---->  2 CO + 6 H₂O

3.5 moles C₂H₆           2 moles CO
-----------------------  x  ------------------------  =  3.5 moles CO

                                  2 moles C₂H₆
