The standard Gibbs free energy of formation of a compound is the change of Gibbs free energy that accompanies the formation of 1 mole of that substance from its component elements, at their standard states (the most stable form of the element at 25 degrees Celsius and 100 kilopascals).
Assuming you mean How much of the water on Earth is fresh water, about 5% of the water on the Earth is fresh water, as opposed to about 95% salt water. To anser your questioâ¦n directly though, 100% of the fresh water we know about is on Earth.
Most of the earth's fresh water is stored as ice in the Arctic and Antarctic regions of the globe. About 1.7% of the earth's entire water supply exists in icecaps. Other useful statistics: Approx. 97.5% of the earth's water is stored in the ocean and is not usable because it is saline. The remaining 2.5% is freshwater: 1.7% is found in ice caps. 0.7% is found as groundwater. 0.02% is found in lakes, streams, rivers, etc. 0.001% is found in the atmosphere. 0.001% is found as soil moisture.
