In the “Méthode Champenoise,” grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is C 6 H 12 O 6 ( a q ) → 2C 2 H 5 OH ( a q ) + 2CO 2 ( g ) Fermentation of 750. mL grape juice (density = 1.0 g/cm 3 ) is allowed to take place in a bottle with a total volume of 825 mL until 12% by volume is ethanol (C 2 H 5 OH). Assuming that the CO 2 is insoluble in H 2 O (actually, a wrong assumption), what would be the pressure of CO 2 inside the wine bottle at 25°C? (The density of ethanol is 0.79 g/cm 3 .)

Fermentation of 750. mL grape juice (density = 1.0 g/cm3) is allowed to take place in a bottle with a total volume of 825 mL until 12% by volume is ethanol (C2H5OH). Assuming that the CO2 is insoluble in H2O (actually, a wrong assumption), what would be the pressure of CO2 inside the wine bottle at 25°C? (The density of ethanol is 0.79 g/cm3.)
