Problem- Calculate the masses of oxygen and nitrogen (in mg) that are dissolved in 1.5 L of aqueous solution in equilibrium with air at 25°C and 760 Torr. Assume that air is 21% oxygen and 78% nitrogen by volume.
Henry's law constants for gases in water at 25 degrees C (bar/M): O2 = 7.9 x10^2, N2 = 1.6x10^3.
I want to know how this is done please show all steps in detail
