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.
More than 68 percent of the planet's fresh water is largely inaccessible, located in glaciers, ice caps and permanent snow. Another 30 percent of the planet's fresh water is located in the ground, within a half-mile of the Earth's surface. The amount of water located on Earth is enough to cover the entire land mass of the contiguous United States to a depth of 107 miles.
