Question

Under identical atmospheric conditions,which of the following is true?
A)Freshwater has more oxygen than seawater
B)Freshwater has less oxygen than seawater
C)Freshwater can hold 10-40 times more carbon dioxide than air
D)Freshwater can hold 10-40 times more oxygen than air
E)Freshwater has higher density but lower viscosity than air.

Accepted Answer

Freshwater has more oxygen than seawater because it has a lower concentration of dissolved salts, which allows for more oxygen to dissolve in the water. Seawater has a higher concentration of dissolved salts, which can decrease the amount of oxygen that can dissolve in the water.
