What mass of oxygen gas, in mg, is dissolved in 4.26×102 ml of water when the partial pressure of oxygen above the water is 1.9 atm at 25 °c? the henry's constant for oxygen gas in water at 25 °c is 0.0013 m/atm.

33.67 mg

Explanation:

Hello,

Since the Henry's constant allows us to know the concentration of the dissolved , we apply the formula:

Now, by knowing the concentration and that the volume is 0.426 L of water (proper units), we apply the following factors to know the milligrams of oxygen gas:
