At a certain temperature, the solubility of n2 gas in water at 2. 38 atm is 56. 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. 38 atm to 5. 00 atm.

Why do you think electric energy for households is generally supplied by power plants instead of by an electric generator at home.
