Molar Mass (g/mol) C (Carbon) 1× 12.0107 = 12.0107 O (Oxygen) 3× 15.9994 = 47.9982 H (Hydrogen) 1× 1.00794 = 1.00794 4. Sum Each Element's Mass Finally, add together the total mass of each element to get the molar mass of CO2OH: 12.0107 g/mol + 47.9982 g/mol + 1.00794 g...
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...

precipitation, with additionally needed alkalinity coming from porewater (that is, a binary mixing model). Assuming thatδ13C of methyl sulphides and carbon isotope fractionation during methanogenesis are –30‰ and –60‰ (ref.44), respectively, mass balance consideration requires thatδ13C of ...
The changes in molar mass, crystallinity and amount of carbonyls were determined. After 498 days the pre-aged EVOH samples exposed to the fungi had the largest amount of evolved 14CO2. Pure LDPE was the least degraded of the three materials compared. The EVOH samples did not, however, show...
