When N2gas is passed through water at 293k. how many moles of N2 dissolve in 1litre water

7 milimoles of dissolve in 1 litre water.

Explanation:

Given:   gas is passed through water at 293K.

Assumption : exerts a partial pressure of 0.987 bar.

Take : Henry's constant = 76.8 Kbar

To find : Number of moles of   gas dissolve in 1 litre water.

According to Henry's law,

moles in 1 liter  of water =

Let n= moles of nitrogen

Total moles = 55.56+n

So,

Hence, 7 milimoles of dissolve in 1 litre water.
