How many grams of nitrogen and oxygen are dissolved in 125g of water at 20.0C when the water is saturated with air, in which Pnitrogen(2) equals 593 torr and Poxygen(2) equals 159 torr? At 1.00 atm pressure, the solubility of pure oxygen in water is 0.00430g O(2)/100.0g H(2)O, and the solubility of pure nitrogen in water is 0.00190g N(2)/100.0g H(2)O.
Determine the number of grams of O2 consumed.
