Explanation:
The moles of carbon disulfide formed from the reaction of 2.7 mole carbon has been 0.54 moles.
The balanced chemical reaction for the formation of [tex]\rm CS_2[/tex] has been:
[tex]\rm 5\;C\;+\;2\;SO_2\;\rightarrow\;CS_2\;+\;4\;CO_2[/tex]
The stoichiometric coefficient in the balanced chemical equation has been the representation of the moles of each reactant and the products.
Computation for Moles of Carbon disulfide
From the balanced chemical equation, for the formation of 1 moles of carbon disulfide, 5 moles of carbon reacts.
The moles of carbon disulfide formed by the reaction of 2.7 moles of carbon has been:
[tex]\rm 5\;mol\;C=1\;mol\;CS_2\\2.7\;mol\;C=\dfrac{1}{5}\;\times\;2.7\;mol\;CS_2\\2.7\;mol\;C=0.54\;mol\;CS_2[/tex]
The moles of carbon disulfide formed from the reaction of 2.7 mole carbon has been 0.54 moles.
