Henry's Law

Q. Air is a mixture of gases that is about 78.0% N2 by volume. When air is at standard pressure and 25.0 degrees C, the N2 component will dissolve in water with a solubility of 4.88 x 10^-4 M. What is the value of Henry's law constant for N2 under these conditions? Express your answer with the appropriate units. Enter the unit M using the compound form mol/L.
