In the "Méthode Champenoise," grape juice is fermented in a wine bottle to produce sparkling wine. The reaction is
C,H12Os (aq) + 2C, H;OH(aq) + 2002(9)
Fermentation of 893 ml grape juice (density is 1.0 g/cm') is allowed to take place in a bottle with a total volume of 971
mL until 15% by volume is ethanol (C,H; OH). Assuming that CO2 obeys Henry's law, calculate the partial pressure of
CO, in the gas phase and the solubility of CO, in the wine at 25°C. The Henry's law constant for CO, is 3.1 x 10-2
mol/L atm at 25°C with Henry's law in the form C = kP, where C is the concentration of the gas in mol/L. (The density
of ethanol is 0.79 g/cm.)
