Hydrogen gas has a Henry’s law constant of 7.8 ×…

Hydrogen gas has a Henry’s law constant of 7.8 × 10?4 mol/kg ? bar at 25°C when dissolving in water. If the total pressure of gas (H2 gas plus water vapor) over water is 1.00 bar, what is the concentration of H2 in the water in grams per milliliter? (See Appendix G in your textbook for the vapor pressure of water.)
