A student is required to prepare 25.0 mL of ethanol using a sucrose fermentation technique. How many mL of carbon dioxide can be expected to fill a balloon used as a trap in the fermentation? (at 20 degrees C and 1.0 atm, the enzymatic system works at 65% efficiency and the solubility of CO2 in water at 20 degrees C is 88mL) The sucrose solution used in the fermentation was 0.350 M. Assume solubility of CO2 in water equivalent to the solubility in the sucrose solution. HINT: some of the CO2 obtained from fermentation dissolves in the solution, the rest goes to the balloon. Disregard water vapor pressure.
