When determining the formula mass for a hydrate, the waters of hydration must be included. Accuracy limits for these expansion curves have been tested by Loh et al., 23 who found, for example, that the allowable 0.6-gravity gas expansion from 23.8 MPa (3,500 psia) and 338 K (150F) should be 2.8 MPa (410 psia), rather than the value of 4.76 MPa (700 psia) given by Fig.5. Hydrate formation with rapid expansion from a wet line is common in fuel gas or instrument gas lines. Get('ml').innerHTML = ""+(ml * env)+""; Rehydrate Pro is a brand created to highlight the need for people Papers coated with cobalt chloride are sold as a way to detect moisture. around 21%. d) To determine the percent of water in a hydrate sample. function trOut() {this.className = def;} The mass of water present in one mole of Gypsum is 36 grams, since within every mole of Gypsum there are two moles of water molecules, and each mole of water molecule weigh 18 grams. Chances are that you arent drinking enough water. 3, the development of more accurate hydrate data and prediction methods have led to the gravity method being used as a first estimate or a check, rather than as a principle method, despite its ease of calculation. In our example, 16 grams / 160 grams per mole = 0.1 moles. Presented at the Offshore Technology Conference, Houston, 30 April3 May. All rights reserved.

Methane hydrate (MH) is a solid compound in which a large amount of methane gas molecules (CH 4) are caged within a crystalline structure of water, as illustrated in Fig. Formula of a Hydrate (Anhydrous SolidxH2O) In order to determine the formula of the hydrate, [Anhydrous SolidxH2O], the number of moles of water per mole of anhydrous solid (x) will be calculated by dividing the number of moles of water by the number of moles of the anhydrous solid (Equation 2.12. While commercial software programs are available to examine phase equilibria, it is useful to understand the basics as a means to evaluate the computer results. In our example, we lost 9 grams of water; if we divide 9 by 18, we get 0.5 moles of water lost. The hydrate's molecular weight is 381.365 g/mol The total amount of water in the molecular weight is 180.148 g. 180.148 / 381.365 = 0.47238 (decimal amount of the hydrate that is water) (5.00 g) (0.47238) = 2.3619 g (this is the water lost) 5.00 g 2.3619 g = 2.6381 g of the anhydrous Na 2 B 4 O 7 remaining Round off to three sig figs: 2.64 g // Show the debug window function zerosPad(rndVal, decPlaces) { All rights reserved | Mass of crucible 3. obj.className = inh; Determine the grams of anhydrate remaining in the crucible. } Water is the only naturally occurring zero-calorie drink.

The abscissa (x-axis) in each figure represents the lowest downstream pressure without hydrate formation, given the upstream pressure on the ordinate (y-axis) and the upstream temperature (a parameter on each line). 186 (12): 185-206. Cs = correction factor for salinity, CG = correction factor for gas gravity. Various factors can increase or decrease the amount of fluid your body needs to function at its best. x m = 1 -exp (-d/72) where: d = depression of the water dew point or gas hydrate freezing point, deg C (>13.5) Vaporization losses are to be calculated as explained previously. 2 (45): 385392. National Institutes of Health. } Scientific studies have come to conclude that men require more water than women on a regular basis, at least 125 ounces daily as compared to a womans 91 ounces. } (1 Cu) (63.55 g/mol) + (1 S) (32.07 g/mol) + (4 O) (16.00 g/mol) = 159.62 g/mol Formula mass = 159.62 g/mol + (5 H 2 0) ( 18.02 g H 2 0/mol) = 249.72 g/mol 2. 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.

For example, how to calculate the percentage error: Suppose you did an experiment to measure the boiling point of water and your results average to 101.5C. 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#. function clear_field(field) { What molecular formula represents a carbohydrate? function showDebug() { ShapeFit is a health and fitness company dedicated to providing the best exercise, nutrition and wellness information and resources to help our visitors get in shape, stay fit and live a healthier and happier life! var theOb = Get( oName, null, oDoc.layers[x].document ); if( theOb ) { return theOb; } } Admittedly this value will vary depending on various factors, with most water requirement calculations executed primarily with gender in mind. }*/ 5 of Sloan.[2]). Multiplying this fraction by 100 gives the percent water. Unfortunately, however, for hydrate precipitation from a vapor or liquid hydrocarbon, there is no water content hand calculation analogous to either Fig. If you've already conducted this experiment and know the mass of both the hydrated and anhydrous salts, the calculations are simple.
