Answer: 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.
