Ntxiv mus, qhov sib txawv tseem ceeb ntawm ob qho tib si yog qhov molar loj muab qhov loj ntawm mole ntawm ib yam khoom. Qhov hnyav molecular yog qhov loj ntawm ib qho molecule ntawm ib yam khoom. Thaum lub ntsiab lus thiab units txawv rau molar mass thiab molecular hnyav, tus nqi yog tib yam
Qhov txawv ntawm molar mass thiab molecular mass yog dab tsi?
Ntxiv mus, qhov sib txawv tseem ceeb ntawm ob qho tib si yog molar mass muab qhov loj ntawm ib mole ntawm ib yam khoomWhereas molecular hnyav yog qhov loj ntawm ib molecule ntawm ib yam khoom. Thaum lub ntsiab txhais thiab cov chav nyob txawv rau molar mass thiab molecular hnyav, tus nqi yog tib yam.
Dab tsi yog molecular formula mass?
Cov mis loj ntawm ib yam khoom yog qhov sib npaug ntawm qhov nruab nrab atomic masses ntawm txhua lub atom sawv cev hauv cov tshuaj formulathiab tau qhia hauv atomic mass units. Cov mis loj ntawm covalent compound tseem hu ua molecular mass.
Yuav ua li cas peb xam molar mass?
Tus yam ntxwv molar mass ntawm ib lub caij tsuas yog cov atomic loj hauv g / mol. Txawm li cas los xij, molar loj kuj tuaj yeem xam los ntawm muab cov atomic loj hauv amu los ntawm cov molar loj tas li (1 g / mol)txhawm rau xam cov molar loj ntawm cov khoom sib xyaw nrog ntau lub atoms, suav tag nrho. lub atomic mass ntawm lub constituent atoms.
Dab tsi yog lwm lub npe rau molar mass?
Qhov hnyav molecular feem ntau yog siv los ua lub ntsiab lus ntawm molar mass, tshwj xeeb tshaj yog rau cov tebchaw molecular; Txawm li cas los xij, cov ntaub ntawv pov thawj feem ntau txhais nws txawv (saib Molecular mass). Cov mis hnyav yog ib lub ntsiab lus ntawm molar mass uas nquag siv rau cov tsis-molecular tebchaw, xws li ionic ntsev.
