Homework Help: chemistry

Posted by Tatiana on Friday, February 11, 2011 at 8:36pm.

I have a lot of trouble doing this chemistry exercise

It says:

The altitude of the lake affects the solubility of oxygen in lakes high in the alps. if the solubility of O2 from the air is 7.89 mg/L M at sea level and 25C, what is the solubility of O2 in moles/L at an elevation of 13,000 ft where the atmospheric pressure is 0.612atm and the temperature is also 25C? Assume that the moles fraction of O2 in air remains constant, at 0.209 at both elevations

Thanks a lot for the help!!!
