Question:

In the “Méthode Champenoise,” grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is

C₆H₁₂O₆(aq) → 2C₂H₅OH(aq) + 2CO₂(g)

Fermentation of 750. mL of 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^oC? (The density of ethanol is 0.79 g/ cm³.)
