3. A bottled soft drink at 25°C contains carbon dioxide at a pressure of 5.0 atm over the liquid. Assuming that the partial pressure of the carbon dioxide gas is 4.0*10-4 atm, calculate the equilibrium concentrations of carbon dioxide in the soda both before and after the bottle is opened. The Henry's Law constant for carbon dioxide in aqueous solution is 3.1*102 mol/Latm at 25°C.

3. A bottled soft drink at 25°C contains carbon dioxide at a
pressure of 5.0 atm over the liquid. Assuming that the
partial pressure of the carbon dioxide gas is 4.0*10-4 atm,
calculate the equilibrium concentrations of carbon dioxide
in the soda both before and after the bottle is opened. The
Henry's Law constant for carbon dioxide in aqueous
solution is 3.1*10² mol/Latm at 25°C.
4. Calculate the expected vapor pressure at 25°C for a
solution prepared by dissolving 158.0 g of sugar (molar
mass=342.3 g/mol) in 643.5 cm³ water. At 25°C, the
density of water is 0.9971 g/cm³ and the vapor pressure is
23.76 torr.
