Extracted text: If 100 mol/hr of fresh feed containing 35 mole% of glucose in water was used in the catalytic process, and that the gross feed to the reactor contains 4.93% fructose, what is the amount of fructose (in moles) in the recycle stream? Assume the ratio of the exit stream to the recycle stream in mass units is equal to 8.71. Recycle Fresh feed, F Glucose Gross feed Glucose Product, P REACTOR Water Fructose Water The answer is approximately 5.50, how was this solved?
