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.
There is not really much fresh ware on Earth. 1.74% of all Earth's water is in this frozen form as ice caps, glaciers and snow. Only 0.75% of Earth's water is liquid water and potentially accessible as fresh water in ground water, lakes, streams and swamps. Long Answer: About 97.5% of water on Earth is salt water and 2.5% fresh water. All of the oceans are salt water and the oceans represent more than 96% of all water on Earth. Of the 2.5% fresh water, only 0.3% is in liquid form on the surface. Most of the rest is frozen or underground. Less than .01 % of all water is in lakes and rivers.
