Homework Help: Gas solubility in water

  1. Jun 12, 2006 #1
    Hello,

    I'm trying to get the concentration (mg/L) of N2, O2 and Ar in air equilibrated water at 1000.9mbar, 20C and 65% humidity (clear water, salinity~0) using the following literature B and k (Bunsen coef and Henry's coef):

    N2
    B=15.57 cc.liter-1 atm-1.
    k=7.97atm*10-4.

    O2
    B=29.86 cc.liter-1 atm-1.
    k=4.15atm*10-4.

    Ar
    B=34.03cc.liter-1 atm-1.
    k=3.65atm*10-4.

    I confuse the unities, once and again, and again, and again...

    Which would be the conc (mg/L) if I dissolve 10mL of air in excess (by hydrostatic pressure).

    thanks a lot,
    merely
