Consider a carbonated drink in a bottle at 27°C and 130 kPa. Assuming the gas space above the liquid consists of a saturated mixture of CO2 and water vapor and treating the drink as water, determine
(a) the mole fraction of the water vapor in the CO2 gas and
(b) the mass of dissolved CO2 in a 300-ml drink.
