Yog li txhawm rau xam cov moles ntawm cov khoom muaj nyob hauv cov qauv, peb tsuas yog faib qhov hnyav ntawm cov khoom los ntawm nws cov molar pawg. Qhov twg 'n' yog tus lej ntawm moles, 'm' yog qhov loj thiab 'M' yog molar mass.
pes tsawg moles?
A mole txhais tau tias yog 6.02214076 × 10 23 ntawm qee chav tshuaj, yog nws atoms, molecules, ions, lossis lwm yam. Lub mole yog ib chav tsev yooj yim siv vim muaj cov atoms, molecules, lossis lwm yam hauv ib yam khoom.
Tus qauv rau mole yog dab tsi?
Avogadro tus lej yog qhov tseem ceeb heev uas yuav tsum nco ntsoov: 1 mole=6.022 × 1023 6.022 × 10 23 atoms, molecules, protons, thiab lwm yam. Txhawm rau hloov los ntawm moles rau atoms, muab cov molar ntau ntxiv los ntawm Avogadro tus lej. Txhawm rau hloov los ntawm atoms rau moles, faib cov atom npaum li cas los ntawm Avogadro tus lej (lossis muab faib los ntawm nws qhov sib txuam).
Yuav ua li cas yog mole hauv chemistry rau dummies?
Tus mole (lub ntsiab lus mol thiab qee zaum hu ua Avogadro tus lej) yog tus lej hloov pauv uas tso cai rau tus kws kho mob lossis kws kho mob kom txav los ntawm lub ntiaj teb microscopic ntawm atoms, ions, thiab molecules mus rau lub ntiaj teb macroscopicntawm grams, kilograms, thiab tons.
Vim li cas mole 6.022 x10 23?
Lub mole (lub ntsiab lus mol) yog SI ntsuas qhov ntau ntawm "cov khoom siv tshuaj", xws li atoms, electrons, lossis protons. Nws txhais tau tias yog tus nqi ntawm cov khoom uas muaj ntau yam raws li muaj atoms nyob rau hauv 12 grams ntawm ntshiab carbon-12. Yog li, 1 mol muaj 6.022 × 10 23 cov khoom tseem ceeb ntawm cov khoom

Muaj moles yuav ploj mus?
Lawv tuaj yeem hloov pauv thiab hloov zuj zus raws sijhawm. Ib txhia moles nws thiaj li poob tag nrho. Thaum noj qab nyob zoo moles ploj, cov txheej txheem feem ntau yog maj mam. Tus mole ploj mus yuav pib raws li qhov chaw tiaj tus, maj mam tsa, tom qab ntawd lub teeb, daj ntseg, thiab thaum kawg ploj mus .
Thaum twg siv tsis muaj tswv vs tsis muaj zog?
Qhov txawv ntawm qhov tsis muaj zog thiab tsis muaj tswv yog qaug zog yog xaiv tau thaum tsis muaj tswv tsis xaiv Los ntawm tshaj tawm tias nws qaug zog koj tau txais rooj plaub uas nws yuav tsis nyob hauv kaw ntawm qee lub sijhawm. Yog tias koj sim nkag mus rau qhov sib txawv tsis muaj npe uas tshwm sim tsis yog, nws yuav tsoo tag nrho cov haujlwm .
Yuav ua li cas tshem tawm cov moles tsis tsa?
Cov kab mob uas tsis yog mob qog noj ntshav uas nyob tsuas yog ntawm daim tawv nqaij qee zaum raug tshem tawm los ntawm freezing lawv tawmYog tias koj thiab koj tus kws kho mob txiav txim siab khov yog qhov zoo tshaj plaws los tshem koj cov mole, koj tus kws kho mob yuav siv cov kua nitrogen kom khov nws tawm.
Puas muaj kev sib cav uas tsis muaj zog thiab tsis muaj kev ntseeg?
Puas muaj kev sib cav uas tsis muaj zog thiab tsis muaj kev ntseeg? piav qhia: Txhua qhov kev sib cav uas tsis muaj zog kuj yuav tsis muaj kev sib cav, vim tias yuav muaj zog yog ib feem ntawm lub ntsiab lus ntawm kev sib cav . Puas muaj kev sib cav uas tsis muaj zog thiab paub?
Puas yog tus tsav tsheb tsis muaj ntawv pov hwm zoo ib yam li tsis muaj ntawv pov hwm?
Kev tuav pov hwm tus neeg tsav tsheb tsis muaj pov hwm tiv thaiv koj yog tias koj raug xwm txheej tus neeg tsav tsheb tsis raug uas tsis muaj kev tuav pov hwm kev lav phib xaub. Tsis muaj kev pov hwm tus neeg tsav tsheb tau txais kev pab cuam nyob rau hauv thaum koj raug xwm txheej nrog tus neeg tsav tsheb ua txhaum uas nws lub luag haujlwm txwv tsis pub dhau los them cov nqi kho mob ntawm cov neeg raug mob .
