PLEASE SHOW ALL WORK/ EXPLAIN

Question 12 0.5 pts The solubility of a gas in water is a function of the identity of the gas, the pressure of the gas over water, and the temperature of the system. For the solubility of oxygen in fresh water shown in the diagram it is assumed that the pressure of oxygen is 1.00 atm. The quality of aquatic life depends on among other parameters, the amount of dissolved oxygen in the water. Factors such as thermal pollution and decomposition of organic matter can significantly alter the oxygen content of a body of water 2.5 2.0 1.5 1.0 0.5 10 20 30 40 50 Temperature, oC What is the millimolar solubility of oxygen gas, O2. in water at 12 °C, if the pressure of oxygen is 1.00 atm? Express your answer numerically, to two significant figures and in terms of mM.

Explanation / Answer

The curve showing the solubilty of oxygen in water in accordance with the temperature is shown in the picture above.

The solubility seems to be more at the lower temperatures and gradually declines as the temperature is increased.

So here when the temperature is 12oC , the millimolar solubility of O2 gas is 1.5 mM
