Final answer:
Using stoichiometry, 17.68 moles of carbon disulfide production would require 17.68 moles of carbon, as the stoichiometry of the balanced equation indicates a 1:1 ratio between carbon and carbon disulfide.
Step-by-step explanation:
The student's question relates to stoichiometry, a concept in chemistry that deals with the quantitative relationships between the substances involved in chemical reactions. If 17.68 moles of carbon disulfide (CS2) are produced, we need to determine the amount of carbon (C) required for this reaction. Assuming the provided reaction is meant to represent carbon combined with sulfur to produce carbon disulfide, the balanced reaction would be:
C + 2S → CS2
This indicates that 1 mole of carbon reacts with 2 moles of sulfur to produce 1 mole of carbon disulfide. To find the number of moles of carbon needed, we use the stoichiometry of the equation:
1 mole of C → 1 mole of CS2
Therefore, if 17.68 moles of CS2 are produced, then 17.68 moles of carbon would be needed to react with sulfur to produce the CS2.
