Molecular Mass: The molecular mass of a chemical species is the sum of the atomic masses of the component elements. This takes into consideration all the naturally-occurring isotopes of the element which is why we use the average atomic mass instead of the atomic mass of the isotope with the...
This research aims to addresses molecular sequestration of NO2 from a gaseous flow applying NaOH absorbent in a hydrophobic porous membrane contactor (HPMC). A mechanistic two dimensional (2D) model is developed based on mass transfer and fluid flow, while computational fluid dynamics (CFD) ...
What is the mass of 9.44 x 1024 molecules of NO2? The molar mass of NO2 is 46.01 g/mol. Define formula mass, molecular mass, and molar mass. How are they similar and how are they different? The density of a gas is 1.96 g/L at STP. What is its molar mass? A) 65.2 g/mol ...

The authors found that smectite with the interlayer cations considered in their investigation was efficient in capturing almost the same mass of carbon dioxide (0.23 ton CO2/m3 of the sample) as in comparison to the zeolite minerals (0.29 ton CO2/m3 of the sample) or metal-organic frameworks ...
All of the complexes were characterized by IR, mass spectrometry, and 1H, 13C, and 119Sn NMR spectroscopies, and the spectra display chemical shifts corresponding to a seven-coordinated tin environment. The crystal structures of complexes 2a, 2d, and 4b were determined by X-ray diffraction. ...
