Answer : The number of moles of carbon sulfide produced are, 1.18 moles.
Explanation : Given,
Moles of carbon = 5.9 moles
The balanced chemical reaction is:

From the balanced chemical reaction we conclude that,
As, 5 moles of carbon react to give 1 mole of carbon sulfide
So, 5.9 moles of carbon react to give
mole of carbon sulfide
Thus, the number of moles of carbon sulfide produced are, 1.18 moles.
