Question 167. How many moles of white phosphorus (P4) can you produce from 1 ton offluoroapatite?D Question 178. How many moles of mixed-metal oxide (Ca3Si207) can you produce from 1ton of fluoroapatite?Question 189. How much money can you make selling off this mixed-metal oxide (Ca3Si207)to the corrupt contractor at 2¢ a pound? IntroductionHome Depot's market research shows that they can sell 20-lb. bags of ammoniumphosphate, a common fertilizer with the chemical formula (NH4)3PO4, for $9.99/bag.This price has been marked up 6% from the wholesale price that they pay to themanufacturer. You decide to use your knowledge of chemistry to produce your ownammonium phosphate and sell it to Home Depot at 5¢ below the wholesale price.You contact a packager, who agrees to package your product for 29¢ per bag.Ammonium phosphate is produced from ammonia (NH3) and phosphoric acid(H,PO4). Ammonia, in turn, can be produced at a 50% yield via the Haber process,using a mixture of hydrogen (H2) and nitrogen (N2) gases with an iron catalyst.Phosphoric acid is obtained from a naturally occurring mineral called fluorapatite,Cas(PO4)3F, by the following process: fluoroapatite is mixed with silica sand (SiO2)and coke (elemental carbon, C) in an electric furnace. The products are carbonmonoxide (CO), tetrafluorosilane (SIF4), white phosphorous (P4), and a mixed-metaloxide with the formula Ca3Si207. Of these four products, only the white phosphorousis useful in producirg phosphoric acid; the other products go to waste. However,a (corrupt) contractor will buy the mixed-metal oxide (to dilute cement used infreeway overpasses) from you for 2¢ a pound. You agree to this (of course notknowing what he intends). The white phosphorus is then burned in oxygen (O2) togive phosphoric acid anhydride, P.010, which is finally reacted with water to givethe desired phosphoric acid.You decide to use air as your source of oxygen and nitrogen gases, so those reagentscome at no cost. Fluoroapatite costs $20/ton, silica sand costs $5/ton, elementalcarbon costs $3/ton, and hydrogen gas costs 9e for 10 yd' at STP, where 1 mole ofgas occupies 22.414 L. Let's ignore the cost of the electricity to run the furnace andto compress and heat the gases, and assume that the iron catalyst is a one-time gift.Let's also assume that water is free.

Given: Mass of Ca5(PO4)3F = 1 ton = 1000 Kg = 106 g.
