Molar Excess Gibbs Free Energy refers to the additional Gibbs free energy associated with the mixing of substances in a system, excluding the contribution from the ideal entropy of mixing and volume effects. It is a measure of the non-ideal behavior of a mixture. ...
ΔH: molar enthalpy change of hydrogen. ΔS: molar entropy change of hydrogen. P: pressure of hydrogen gas. X: = H/M, where H and M represent the numbers of hydrogen atoms in the hydride and metal atoms for unit formula of hydride, respectively. View chapterExplore book...
I have 370mL of 20g/L NaCl solution. After boiling it for 15 minutes, the volume is reduced to 275mL. What will be the concentration of NaCl in the final solution? You want to make 406 mL of a solution with a concentration of 350 g/L. How much solute...
In order to calculate the molar mass of any compound, we only need to know what elements are contained in the compound and what the molar mass of the elements are. Answer and Explanation: The molar mass of sucrose is 342.2965 g/mol. Let's look at the math. ...
light gas oil or lubricating oil, the mole ratio of hydrogen in the recirculating gas, to the hydrocarbon in the oil is computed on the basis of sensed parameters in the system, and maintained at a desired value to minimize coking of the catalyst, by controlling the speed of a compressor ...

Concerning the second virial coefficient (A2), it is usually neglected because when SEC is used, the polymer concentration at each elution volume is very low and thus the contribution of A2 to the polymer molar mass is very low. Therefore, the molar mass and size information (rg) (in the...
Excess molar volumeInter molecular hydrogen bondingConsistent vapor–liquid equilibria (VLE) data at 95.3kPa have been determined for the binary mixtures of N-methyl-2-pyrrolidone (NMP) +2-methoxyethanol (2-ME), +2-ethoxyethanol (2-EE), +2-butoxyethanol (2-BE) over the entire composition ...
and the substance added is called the solute. If both components are liquids, the distinction loses significance; the one present in smaller concentration is likely to be called the solute. The concentration of any component in a solution may be expressed in units ofweightor volume or inmoles....
