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...
