5 L of an apple juice in a container was saturated at a pressure of 6 atm and a temperature of 25 oC with air and sealed. The Henry’s Law constants for nitrogen and for oxygen are 6.1×10-4 mol L-1 atm1 and 1.3×10-3 mol L-1 atm-1 respectively. (i) Calculate the molarity and the mass of nitrogen and oxygen dissolved in the juice. (ii) Calculate the mass of nitrogen (N2) and the mass of oxygen (O2) released when the container was opened at air pressure 1 atm and temperature 25 oC. (iii) Calculate the volume occupied by the gas released from the container under the above conditions. Neglect the contribution of other gases to the volume. Assume that the gases are idea.
78% nitrogen
21% oxygen

Henry’s law states that the solubility of a gas is directly proportional to the partial pressure of the gas if the temperature is constant. Hyperbaric chambers, which provide high pressures (up to 6 atm) of either air or pure oxygen, are used to treat a variety of conditions, ranging from decompression sickness in deep-sea divers to carbon monoxide poisoning. Look up the Henry’s Law Constant (kH) for N2, O2, and CO2 in the textbook. a) Calculate the solubility (concentration in...
