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, C ₁₂ H ₂₂ O ₁₁ ) 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 Ibmol/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 a 17 lb _m /hr. Finally, vanilla ex-tract is fed at a rate corresponding to 1 lb _m of extract for every 30 lb,, 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 /ft ³ ). What are the mole percentages?
