Carbon disulfide, CS2, can be obtained from coke (C) and sufur dioxide (SO2): 3C + 2 SO2 CS2 + CO2 If the actual yield is 78.9% of the theoretical yield, what mass of coke is needed to produce 786 g of CS2?
percentage yield = actual yield/theoritical yield
theoritical yield = actual yield/percentage yield
= 786/0.789 = 996.19g
3C + 2 SO2---------------> CS2 + CO2
1 mole of CS2 to produced from 3 moles of C
76g of CS2 to produced from 3*12g of C
996.19g of CS2 to produced from = 3*12*996.19/76 = 471.879g of C
