One of the detrimental effects of the "thermal pollution" of water supplies is that a rise in temperature reduces the amount of dissolved oxygen available to fish. Using the information in the table of Henry's Law constants (KH) below, calculate how many litres of water a fish requires at 30.0°C to obtain the same amount of oxygen that it could obtain from 3.05 L of water at 25.0°C.
