Human bodies have a great dependence on water, not only to fight against dehydration and quench thirst but to improve health which aids the various body organs in executing their functions without hindrance. You take a sample of the hydrate, weigh it, and find it has a mass of 4.13 g. You then heat the sample in order to remove the water and find the weight of the anhydrate to be 3.52 g. The first thing to do is to determine the moles of water that were in the sample, #(4.13-3.52)# #"g" * ("1 mole water")/("18.0 g") = 0.034# #"moles"#, You now go on to determine the moles of the anhydrous salt, #BaCl_2#, #3.52# #"g" * ("1 mole"BaCl_2)/("208.2 g") = 0.017# #"moles"#, The mole ratio between the water and the anhydrous salt is, #("moles of water")/("moles of anhydrate") = 0.034/0.017=2#. That means this: CuSO 4 ---> 74.7 g H 2 O ---> 25.3 g 2) Change to moles: CuSO 4 ---> 74.7 g / 159.607 g/mol = 0.468 mol H 2 O ---> 25.3 g / 18.0 g/mol = 1.406 mol 3) Divide by the smallest: CuSO 4 ---> 0.468 mol / 0.468 mol = 1 Fig. Web Design & 160, SPE-945065-G, 65-76. Dehydration of the gas to prevent the condensation of a free water phase. 49, No. Calculate the percent water in the hydrate sample, using Equation 2 Equation 2 (percent water in a hydrate) percent water, % = (mass of water lost, g/mass of hydrate heated, g) (100%) In this experiment, you will. new Array(93,0,3120), new Array(93,20,3600), new Array(93,40,3960), new Array(93,60,4320),
Every individual has different water consumption requirements, and you should always drink when you are thirsty.
The calculation could be done equally well for MEG, substituting appropriate constants in Eq. Gas gravity is defined as the molecular weight of the gas divided by that of air. What are the name and the formula of the hydrate? 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. The gas flowing through the pipeline is cooled to 38F by the surrounding water. Calculating the amount of water you need to drink daily is more complicated than you may think. Myth or fact: hydration influences your stress level. 4, one can calculate the total amount of hydrate inhibitor needed, as shown below in Example 2.
