The purpose of this lab is to calculate the chemical formula of a hydrate compound made up of copper, chlorine, and water molecules by using the law of definite proportions. Body weight is just as crucial a consideration, with many scientific studies suggesting that human beings need to consume about half their body weight in ounces of water to maintain proper hydration, possibly even losing weight as a result (excessive consumption of water, of which half of ones body weight can appear excessive, which has a tendency to create a feeling of fullness, reducing food consumption). Hydrate Engineering, Vol. 4) Determine the mass of 0.0112 mol of Na2CO3. The difference between the original water and the water remaining in the gas is the mass of liquid water from condensation: 600 9 = 591 lbm/MMscf. Principal.
