The difference in mass between the anhydrous and hydrated salt gives you the information you need to find the percentage of water in the hydrate. For the hydrate equilibrium temperature (, Calculate hydrate formation conditions using the gas gravity chart (. How do you calculate hydrates? Percent error is determined by the difference between the exact value and the approximate value of a quantity, divided by the exact value and then multiplied by 100 to represent it as a percentage of the exact value. Indeed, as theHarvard School of Public Healthpoints out, good hydration keeps the body functioning properly, lubricates joints, and regulates body temperature. }
