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...
Table salt isan ionic compound, which breaks into its component ions ordissociatesin water. These ions are Na+and Cl-. The sodium and chlorine atoms are present in equal amounts (1:1 ratio), arranged to form a cubic crystal lattice. The molecular formula of table salt—sodium chloride—is...

As concentration of particles in the solution is doubled, value of colligative property is double than expected value and hence molecular mass is halved, i.e. observed molecular mass = 58.5/2 = 29.25
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 ...
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
To investigate other sugar nucleotides, we compared the initial velocities of AaNGT using UDP-Glc, UDP-Gal, and UDP-Glc mimetics (UDP-2F-Glc and UDP-5S-Glc), being the latest prepared according to our previous methodologies29 (see Supplementary Figs. 3 and 4 and “Methods” section). We...
