CO2 in water has a Henry’s law constant KB = 1.25 × 106 torr. How many liters of CO2 are needed to make 1 liter of sparkling water at 1 atm and 300 K? The density of water is 1 kg/L and it does not change as CO2 is dissolved. N.B. Treat gas as a solute, and note that in order for water to “sparkle” the partial pressure of CO2 in the vapor phase must equal the atmospheric pressure (note that this neglects the partial pressure of the water vapor).
