Molar loj ntawm H2SO4 tuaj yeem xam los ntawm kev sib tham molar pawg ntawm tag nrho cov elementconstitutingit. Molar loj ntawm H(x2)+ Molar loj ntawm Sulphur(x1)+ Molar loj ntawm Oxygen (x4). = 98g/mol.
Kuj nug, qhov hnyav molecular ntawm h2so4 yog dab tsi?
98,079 g / mol
Ib yam li ntawd, kuv yuav xam qhov hnyav molecular li cas? xam tag nrho qhov hnyav rau txhua lub hauv paus molecule . Muab cov atomic loj ntawm txhua lub caij los ntawm thenumberof atoms ntawm lub caij: (Atomic Mass of Element) x (# ofatoms of that element). Ua qhov no rau txhua lub hauv paus molecule . Inour carbon dioxide piv txwv, qhov loj ntawm cov pa roj carbon atom yog 12.011 amu.
Tsis tas li ntawd, koj yuav pom qhov hnyav sib npaug ntawm h2so4 li cas?
Qhov hnyav sib npaug Tej zaum yuav raug xam los ntawm molarmasses yog tias chemistry ntawm cov khoom paub zoo: sulfuricacid muaj molar pawg ntawm 98,078 (5) gmol−1, thiab muab ob molesofhydrogen ions ib mole ntawm sulfuric acid , suav sib npaug yog 98,078(5)gmol−1/2 ua eq mol−1 = 49.039(3)g ua eq −1.
Qhov feem pua oxygen los ntawm qhov hnyav hauv h2so4 yog dab tsi?
Ib feem pua ntawm cov khoom
| Element | Cim | Pawg Feem Xyuam |
|---|---|---|
| Hydrogen | H | 2.055% |
| Oxygen | O | 65.251% |
