Nitrogen is dissolved in water with the total pressure of gas (Nitrogen + water vapor) over the water being?

Question

2.60 atm. The temperature is 25o C. What is the concentration of Nitrogen in the water?
Give your answer in g/L .
The vapor pressure of water at 25.0oC is 23.8 mm Hg.


Note that kH has units of mol/L / mm Hg

Answer 1

I think you need a numerical value of the Henry Law Constant to solve this. You can find the partial pressure of nitrogen in the gas, but without Kh, you can relate that to the content in liquid.

Answer 2

use
Pv= nRT
