Elemental phosphorus can be produced by heating calcium phosphate from rocks with silica sand (SiO2) and carbon in the form of coke. The following reaction takes place. Ca3(PO4)2 3SiO2 5C £ 3CaSiO3 2P 5CO a. If 57 mol of Ca3(PO4)2 is used and 101 mol of CaSiO3 is obtained, what is the percentage yield? b. Determine the percentage yield obtained if 1280 mol of carbon is consumed and 622 mol of CaSiO3 is produced. c. The engineer in charge of this process expects a yield of 81.5%. If 1.4 105 mol of Ca3(PO4)2 is used, how many moles of phosphorus will be produced?
