Molarity is the number of moles of a substance in 1 liter of the solution. Another unit of the concentration, weight percentage, refers to the ratio of the mass of the solute (a dissolved substance) to the mass of the solution. Converting between concentrations is frequently required for ...
Divide the mass of the substance in grams by its molecular weight. This will give you the number of moles of that substance that are in the specified mass. For 12 g of water, (25 g)/(18.015 g/mol) = 0.666 moles. When dividing by two units that both use grams in their measurement ...
The ethene was then pulsed into the systems and the effluent (ethane or ethene) was detected by mass spectrometer. As shown in Fig. 3b, an obvious larger ethane pulse peak was observed for Ru/SiO2 with the peak area ratio of ethene to ethane (R) reached 5.5. However, the formation of...
In comparison, the mass spectrum of propylene exhibits the strongest peak at m/z = 42, which is similar to the reference 12C3H6 (Fig. 4d) except that the m/z value is shifted by 1 unit (Fig. 4j). Additional weak peaks located at m/z = 44 and 45 are also observed. ...
The procedure is based on using a mass balance of individual molecular species coupled with individual mass transfer rates. Since the surrounding media is assumed insoluble in the finite media, the total number of moles transferred across the interface is computed on the basis of modified molar ...
Inductively coupled plasma mass spectrometry showed that both the wild-type as well as recombinant enzymes contained 2 moles of zinc but variable amounts of manganese/mol of protein subunit. The inactive metal-free apoenzyme could be reactivated by Zn 2+ or Mn 2+. Thus, trans-DLH is a Zn ...
The atomic nuclei corresponding to a given element (i.e., a given atomic number Z) exist in slightly different masses because they may contain different numbers of neutrons (a neutron has a mass nearly equal to that of a proton but no electric charge at all). The total number of nucleon...
chromatography coupled with high-resolution mass spectrometry. Multivariate data analysis was employed to find correlations and differences among the huge number of data obtained and to identifySalviaspecies with similar phytochemical and/or antioxidant properties. The results show that eachSalviaspecies is...
11 allow computing \lambda from mass balanced reactions with examples coming from a variety of biological process. MTS theory demonstrates on a theoretically explicit ground a growth rate expression \mu of a culture of bacteria limited by an electron donor in perfectly mixed conditions6. More ...
