C6H12O6 --> 2CH3CH2OH + 2CO2. the molar mass of glucose is 180.15 g/mol, the molar mss of ethanol is 46.08 g/mol, and the molar mass of carbon dioxide is 44.01 g/mol. What is the theoretical yeild in grams of ethanol from the fermentation of 59.5 g of glucose? If the reaction produced 23.4 of ethanol, what was the percent yield?
