Answer
0.96 mole of $CO$ is produced when 1.2 moles of C reacts.
Work Step by Step
1. Find the mole-mole conversion factors:
According to the coefficients: 5 moles $C$ = 4 moles $CO$
$\frac{ 5 \space moles \space C}{ 4 \space moles \space CO}$ and $\frac{ 4 \space moles \space CO}{ 5 \space moles \space C}$
2. Use the mole-mole conversion factors to calculate the amount of equivalent $CO$ in moles:
$ 1.2$ moles $C \times \frac{ 4 \space moles \space CO}{ 5 \space moles \space C} = 0.96$ mole CO
