You should be careful to not confuse how much water you need with how much water you need to drink. Just as knowing the V and LHC saturation conditions allows the engineer to avoid solid hydrate formation, determining the I-H region (below 273 K) lets the engineer avoid ice or hydrate formation, both of which cause flow problems. For the two-phase regions of hydrate equilibria (i.e., V-H, LHC-H, and I-H), the key question is that of water content: how much water can a vapor or liquid hydrocarbon phase hold before hydrates will precipitate? Clathrate Hydrates of Natural Gases, second edition. Divide the mass of water lost when you heated the salt by the molar mass of water, roughly 18 grams per mole. Every cell, tissue and organ in your body needs water to function correctly. Such measures of expenditure use highly accurate methods and thus TDEE has been set based on solid data rather than the compromise inherent in the Adequate Intake estimations made for water. Jr. 1998. We will then add the mass of the water to the mass of anhydrous salt to get the total mass of the hydrate.
