Answer : The solubility of nitrogen in water at an atmospheric pressure will be,

Explanation :

First we have to calculate the partial pressure of nitrogen.

Formula used :

where,

= partial pressure of nitrogen = ?

= mole fraction of nitrogen =

= atmospheric pressure = 0.480 atm

Now put all the given values in the above formula, we get :

Now we have to calculate the solubility of nitrogen in water.

Formula used :

where,

= partial pressure of nitrogen = 0.375 atm

= solubility of nitrogen in water = ?

= Henry's constant =

Now put all the given values in the above formula, we get :

Therefore, the solubility of nitrogen in water at an atmospheric pressure will be,
