In a candy company, separate streams of sugar, butter, corn syrup, cocoa, vanilla extract, and milk enter a mixer-boiler and come out as fudge. The sugar (sucrose, C₁₂H₂₂O₁₁) is purchased from a sugar farmer who used to be a chemist and who packages it by the lbmol, and the process uses 1.75 lbmol/hr. Butter is fed to the process at a rate of 60 lb_m/hr, corn syrup is fed at a rate of 3.5 gal/hr, and cocoa is fed at 17 lb_m/hr. Finally, vanilla extract is fed at a rate corresponding to 1 lb_m of extract for every 30 lbm of sugar. How many gallons of milk per hour must be fed to the process for a total fudge production of 830 lb_m/hr? (Assume that both the corn syrup and milk have densities equal to 62.4 lb_m/ ƒt³.) What are the mole percentages?
