Last updated: 7/4/2023

The Henry law constant for N and O2 gas dissolved in water at 298K are 6 x 109 N m and 2 5 109 N m A sample of water at 298K was equilibrium with air containing 20 mole oxygen and 80 mole nitrogen at 1 atm If the dissolved gases were separated from a sample of this water and then dried Then calculate the mole of oxygen gas in the dried gaseous sample
