The calculated values of the parameter were independent of molar mass. The parameter did not change significantly with the variation of the salt concentration in water, its values being in the range from 1.10 to 1.19. The values of exponent i in the loglog dependence of Rg, Rh, and R路 ...
Molar Mass: 58.44 grams per mole Appearance: Pure sodium chloride forms odorless, colorless crystals. Many small crystals together reflect light back, making the salt appear white. The crystals may assume other colors if impurities are present. Other Properties: Salt crystals are soft. They are al...
例如：molar mass of CO2 = 44 g/mol； molar mass of NaCl = 58.5 g/mol 简单来说，只有 molar mass 的 unit 是 g/mol，而其他都是没有 unit 的 relative mass。以 H2SO4 为例（Pure H2SO4 is molecular）： Relative atomic mass of H = 1 Relative atomic mass of S = 32 Rela...

This was attributed to the viscosity induced slow mass transfer. At 1 M HNO3, the D values for uranyl and thorium follow the trend C4mimNTf2 > C6mimNTf2 > C8mimNTf2, which was ascribed to the enhancement in organophilicity of the cation on increasing the length of the side chain and ...
Sodium appetite is a motivational state involving homeostatic behavior, seeking the ingest of salty substances after sodium loss. There is a temporal dissociation between sodium depletion (SD) and the appearance of sodium appetite. However, the responsib
Naked mole-rat (NMR), the longest-living rodent, produces very-high-molecular-mass hyaluronan (vHMM-HA), compared to other mammalian species. However, it is unclear if exceptional polymer length of vHMM-HA is important for longevity. Here, we show that vHMM-HA (>6.1 MDa) has superior ...

The measured molecular weights in 0.05 M buffer agree with the mass of the intact (tetrameric) hemoglobin molecule. The apparent relative de-crease in molecular weight found in 2 M salt is too small to be considered significant in the case of carbon monoxyhemoglobin and is questionable for ...
