In the "Methodé Champenoise," grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is )) C6H1206(aq) → 2C2H50H(aq) + 2C02(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 12.5% by volume is ethanol (C,H;OH). Assuming that the Co, is insoluble in H,0 (actually a wrong assumption), what would be the pressure of CO, inside the wine bottle at 25°C? (The density of ethanol is 0.79 g/cm3)
