At a certain temperature, the solubility of N2 gas in water at 2.04 atm is 48.0 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 2.04 atm to 6.00 atm . Express your answer numerically to three significant figures.
