Carbon disulfide, CS2 can be made from coke, C and sulfur dioxide, SO2: 3C + 2 SO2→ CS2 + CO2. If the actual yield of CS2 is 86% of the theoretical yield, what mass of coke is needed to produce 950g of CS2?
Now, let's convert this value to moles, using the molar mass of carbon disulfide:
Now, we use the coefficients of the chemical equation to find the relative number of moles of
Finally, we use the molar mass of coke (carbon) to find the mass:
