Composition average

It is a black powder, often pyrophoric, and is non-stoichiometric. the formula Feo.950 more correctly representing its average composition. 

Average composition of grasses grown in temperature zone. 

The dehydration process in Norway has as its raw material basis brine from the potash industry of the following average composition 33% MgCl2 1—2% magnesium sulfate [7487-88-9], MgSO 0.5% sodium chloride [7647-14-5], and 0.2% potassium chloride [7447-40-7],...

In operation, a batch of liquid is charged to the pot and the system is first brought to steady state under total reflux. A portion of the overhead condensate is then continuously withdrawn in accordance with the established reflux pohcy. Cuts are made by switching to alternate receivers, at which time operating conditions may be altered. The entire column operates as an enriching section. As time proceeds, composition of the material being distilled becomes less rich in the more volatile components, and distillation of a cut is stopped when accumulated distillate attains the desired average composition. 

The average composition of the stream leaving a continuous mixer is the same as the average of the added entering streams. Variations in proportions of the entering streams will be damped out by the mixing action of a continuous mixer. These effluent-stream variations will become smaller as average solids residence time is increased and the frequency of the variations increases. 

The phase diagram describes the equilibrium constitution of the alloy - the one given by very slow cooling. In the last example all the liquid should have solidified at the point marked 2 on Fig. A 1.35, when all the solid has moved to the composition Xp = 80% and the temperature is 255°C. Rapid cooling prevents this the solid has not had time to move to a composition Xpp = 80%. Instead, it has an average composition about half-way between that of the first solid to appear (Xpp = 90%) and the last (Xpp = 80%), that is, an average composition of about Xpp = 85%. This "rapid cooling" solidus lies to... 

Here the permeability of the membrane to the solute is defined in terms of reflection coefficients aQ and for osmosis and filtration respectively. When (To = 1, then perfect semi-permeabihty results. in Eq. (4) is the diffusive permeabihty of the membrane, while (Cj) is the average composition of the solute in the membrane. 

A polymer was, therefore, designed to overcome these shortcomings. Its chains with an average composition shown below carried both CBra group and polymerizable metharylate units 161].

The average composition in the condenser (vapor) = 95.7% propane, 4.3% butane, average temp. = 100°F... 

On the other hand, both reduction and thermal-dissociation reactions will result in an increase in weight (equivalent to the solute deposited) and a slight increase in dimensions which will depend on the average composition of the diffused layer.

X-ray absorptiometry can be used to establish not only the average composition of a material, but its lack of uniformity as well. Owing to the high intensity attainable in polychromatic beams, it is possible to... 

We wish to repeat here the warning at the end of Section 9.9. A point source when needed is a fine thing when not needed, it may give misleading information unless the sample is uniform in composition, as most are not. Scanning with a microprobe will give information on average composition. 

The copolymer composition equation only provides the average composition. Not all chains have the same composition. There is a statistical distribution of monomers determined by the reactivity ratios. When chains are short, compositional heterogeneity can mean that not all chains will contain all monomers.
