Asked by Priya

If a gaseous sample contains 74% N2 by volume, what is the solubility of N2 in water at 25°C and 1.0 atm (kH in H2O at 25°C = 7.0 10-4 mol/Latm)?
Answered by DrBob222
C = K*p. The mol fraction N2 is 0.74 and partial pressure (pN2) = 0.74 x total P or 0.74 x 1 = 0.74 atm
Then C = 7.0E-4 x 0.74 = ?M
