Suppose 12.0 g of carbon (C) reacts with 73.0g of sulfur (S) to give 76.0 g of the compound carbon disulfide (CS2). In the process all the carbon gets used up but some elemental sulfur is left over. For the law of conservation of matter to be obeyed how much sulfur is unused? What is the percent C in CS2? What is the percent S in CS2? What is the sum of the %C and %S in CS2?
