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.
If the amount of fresh water is constant on Earth then why do we need to conserve it? What is the percentage of fresh water on the Earth? Why does on the earth only 3% fresh water and rest 97% about sea water? Why Earth contains so much saline water than fresh water? Is the total amount of water on Earth always constant?
