A fermentation process for producing bioethanol from sugar beet pulp yields a fermentation broth containing 70 kg bioethanol, 22 kg sucrose, 8 kg glucose, and the rest is water. If the mass and volumetric flow rates of the broth are 920 kg/hr and 1100 litres/hr. respectively, determine 3 1. the mass fraction of bioethanol in the broth 2. molar mass of the broth 3. mole fraction of glucose and
