5. (20 pts) Food - processing waste with the blodegradable part 80% (weight/weight) which can be shown by empirical formula CH2O can be digested to methane and carbon dioxide, Calculate the content of methane in biogas (volume/volume) and maximum yield of methane in terms of kg CH4 / kg of food-processing waste with the empirical formula CH20. Assume that a fermentation of the food-processing wastes can be described by the following equation: 6CH20 3CH4 + 3CO2 Neglect the solubility of the gases in water Given: The molecular weight of food-processing waste (CH0), CH, and CO2 are 30, 16, and 44 grams/mole, respectively
