A vessel contains water and hydrogen in 2 phases, i.e., liquid and gas. The vessel is at 100 bar(abs), 10 C. The vapour pressure of water at 10 C is 0.01 bar(abs). Henry's law constant for hydrogen in water, at 10 C is HHw = 62 000 bar. What is the mol fraction of hydrogen in liquid water? Express your answer in molar parts per million (mol ppm) of hydrogen in water.
