At a certain temperature, the solubility of n2 gas in water at 3.08 atm is 72.5 mg of n2 gas/100 g water . calculate the solubility of n2 gas in water, at the same temperature, if the partial pressure of n2 gas over the solution is increased from 3.08 atm to 8.00 atm . express your answer numerically to three significant figures.

According to Henry's law, solubility of solution is directly proportional to partial pressure thus,

Solubility at pressure 3.08 atm is 72.5/100, solubility at pressure 8 atm should be calculated.

Putting the values in equation:

On rearranging,

Therefore, solubility will be 1.88 mg of gas in 1 g of water or, 188 mg of tex]N_{2}[/tex] gas in 100 g of water.
