The Henry's law constant for nitrogen in water at 25oC is 6.10 x 10-4 M/atm. What is the concentration (molarity) of nitrogen in water at a pressure of 23.6 atm?

The concentration of nitrogen gas is 0.0144 M

Explanation:

To calculate the molar solubility, we use the equation given by Henry's law, which is:

where,

= Henry's constant =

= molar solubility of nitrogen gas

= partial pressure of nitrogen gas = 23.6 atm

Putting values in above equation, we get:

Hence, the concentration of nitrogen gas is 0.0144 M

the answer is 0.8m.
