Kilogram-moles

NOTE To convert pound-moles to kilogram-moles, multiply by 0.454. 

NOTE Rehoiler duty = 1,549,000 Btn/h. To convert degrees Fahrenheit to degrees Celsius, C = ( F — 32)/1.8 to convert pound-moles per hour to kilogram-moles per hour, multiply by 0.454 and to convert pound-moles to Idlogram-moles, multiply by 0.454. 

For applications where the solution temperature changes, chemists prefer to use the molality, units of mol/kg). Molality is defined to be the number of moles of solute divided by the mass of solvent in kilograms. Moles of solute solute... 

The mean molality values m (moles per kilogram), mole fractions x (dimensionless number) and concentrations c (moles per cubic decimetre) are related by equations similar to those for non-electrolytes (see Appendix A). 

There is often some confusion between the terms standards and reference materials. Primary standards represent the top-tier of chemical standards and, in principle, provide a means of establishing the traceability of analytical data to the SI measurement units (e.g., the kilogram, mole, meter, and second). A limited number of pure chemicals are recognized as primary standards (and thus can constitute certified reference materials). Most certified reference materials are not of themselves primary standards rather, the property values assigned to them are traceable to primary standards where practical. 

FIG. 14-9 O Connell correlation for overall column efficiency for absorption. H is in lb mol/(atm-ft3), P is in atm, and ]l is in cP. To convert HP/[i in pound-moles per cubic foot-centipoise to kilogram-moles per cubic meter-pascal-second, multiply by 1.60 x 104. [O Connell, Trans. Am. Inst. Chem. Eng., 42,... 

FIG. 14-78 Mass-transfer coefficients versus average gas velocity—HC1 absorption, wetted-wall column. To convert pound-moles per hour-square foot-atmosphere to kilogram-moles per second-square meter-atmosphere, multiply by 0.00136 to convert pounds per hour-square foot to kilograms per second-square meter, multiply by 0.00136 to convert feet to meters, multiply by 0.305 and to convert inches to millimeters, multiply by 25.4. [Dobratz et al., Chem. Eng. Prog,49, 611 (1953).]... 

Convert the natural gas flow rate to kilogram-moles per second. At the conditions of this problem, the ideal-gas law can be used. Thus, n = PV/RT, where n is number of moles, P is pressure, V is volume, R is the gas constant, and T is absolute temperature. 

Component Kilogram-moles X Kilograms per mole = Kilograms... 

One must specify whether the value of Avogadro s constant is expressed for a gram-mole or a kilogram-mole. A few books prefer a kilogram-mole. The unit name for a gram-mole is simply... 

Though it seems inconsistent, the SI base unit is the gram-mole. As Mario Iona reminds me, SI is not an MKS system. Some textbooks still prefer to use use the kilogram-mole, or worse, use it... 

Most technical recipes for azo dye preparation call for 1 gram mole or 1 kilogram mole of an amine, since then the quantities of nitrite, acid, and alkali to be used are always the same. Hence, to the technical chemist, the expression "the yield corresponds to 35 grams of nitrite, means that the actual yield is about 50 per cent... 

We shall start out with 1 kilogram-mole, multiplying the quantities given on page 262 by 10,000. 

NOTE To convert pound-moles per hour to kilogram-moles per second, multiply by 1.26 x 10". ... 

NOTE To convert pound-moles per minute to kilogram-moles per minute, multiply by 0.454 to convert pound-moles to kilogram-moles, multiply by 0.454. 

Absolute mass—Masses such as grams, kilograms, and tonnes. Masses such as gram-moles, kilogram-moles, and tonne-moles are relative masses, because they are normalizations. 

Define a kilogram mole, pound mole, and gram mole. 

Furthermore, there is no reason why you cannot carry out computations in terms of ton moles, kilogram moles, or any corresponding units if they are defined analogously to Eqs. (1.4) and (1.5) even if they are not standard units. If you read... 

What is the difference between a kilogram mole and a pound mole ... 

Convert 39.8 kg of NaCl per 100 kg of water to kilogram moles of NaCl per kilogram mole of water. 

Adding these quantities together gives the total kilogram moles.
