Title: Formula of a Hydrate. Objective: Determining the percentage of water and the chemical formula of a hydrate. Background: Water has a polar structure and it has positively and negatively charged parts within each molecule. This gives it a strong attraction toward ions. The ions in some salts attract and form strong bonds with water molecules. These salts‚ when they have absorbed water‚ are called hydrates. Anhydrous salts are salts that can form hydrates but which have had all the water

(re2 / r2) g Acceleration due to gravity inside the Earth Here let r represent the radius of the point inside the earth. The formula for finding out the acceleration due to gravity at this point becomes: g’ = ( r / re )g In both the above formulas‚ as expected‚ g’ becomes equal to g when r = re.
