The rule of additive addition of densities and molar volumes is proved for mixtures of these salts. The molar concentrations of ions present in the mixture are calculated. The dependences of the concentration of each ion on the temperature and the molar fraction of aluminum chloride can be ...
Pure water has a density of 1.00 g/ml at 297 K. Calculate the molar concentration of pure water at this temperature. What is the total molar concentration of all the ions in 0.040 M solutions of the following salts in water? (a) 0.040 M KCI (b) 0.040 M CUSO_4 (c) 0.040 M CaCl...
Molar concentration is a measure of the quantity of certain molecules, atoms, or ions in a solution. The molar concentration, μ, is defined as the number of moles per unit volume: μ=NmolNA⋅v , where Nmol is the number of molecules of a given type present in the volume, v, of...
Here we consider molar concentration, which is measured as the ratio of the amount of substance in moles to the total volume of the solution. The substance in our case is the solute, while the volume is measured for the entire solution, even if it has other solutes in it. Here the ...
A general method is presented for estimating concentration-dependent partial molar volumes for individual ions of heavy density gradient salts used in the isopycnic ultracentrifugation of charged macromolecules. 关键词: Partial molar volume Density gradient Isopycnic centrifugation DOI: 10.1016/0304-4165(79...
From the results, it was found that the drag reduction limitation becomes larger when the molar ratio of the counter-ions to surfactants is set around 20 for each surfactant concentration. From the detailed discussions, the drag reduction characteristics in a higher range of the molar ratio of ...

25 grams of NaOH (MW = 40) are added to 750 ml water, what is the molarity of this solution? 25 mL of NaOH 0.16 M is added to 50 mL of 0.1 M HCl. What is the concentration of hydroxide ions in the solution? If you add water t...
Molar absorption coefficients are used in metalloprotein studies dually: to establish the metal ion concentration and to quantitatively monitor competition with macromolecules to determine the metal binding affinities of the macromolecules. In both cases, anyone using the molar absorption coefficient and ...
