Carbon disulfide is an important industrial solvent. It is prepared by the reaction of coke with sulfur dioxide. 5 C (s) + 2 SO2 (g) - - > CS2 (l) + 4 CO (g) How many moles of CS2 form when 2.79 mol C react?

the balanced equation for the above reaction is as follows;

5 C (s) + 2 SO ₂ (g) - - > CS ₂ (l) + 4 CO (g)

stoichiometry of C to CS ₂ formed is 5:1

5 mol of C react to form 1 mol of CS₂

1 mol of C form - 1/5 mol of CS₂

therefore when 2.79 mol of C react - 1/5 x 2.79

number of CS₂ moles formed - 0.56 mol
