1. The problem statement, all variables and given/known data 1) What is the mass of 100% Ethanol? 2) How much ethanol would be expected from 18% glucose solution? 3) What else will be generated? How can we calculate this amount? Given: Fermentation Equation: C6H12O6(aq) + 2C2H5OH(aq) + 2CO2(g) + Heat (glucose) (ethanol) (carbon dioxide) Molecular Weight of Ethanol = 46.7 g/mol Density of Ethanol = 0.789 g/cm3 2% glucose solution contains 20g/L of glucose 2. Relevant equations D=M/V 3. The attempt at a solution To be honest I'm not sure where to start to attempt this question. A friend of mine sent me this question last night for her assignment and I was stumped. I just wanted to know if someone could help explain how I could find the mass of ethanol with only the variables given to me. I've asked my friend and she keeps insisting there were no other variables. I haven't touched chemistry in years and was just wondering if someone could refresh my memory.
