- Moles thiab Molar daws (unit = M = moles / L)
- Feem pua Kev daws teeb meem (% = seem ib puas lossis grams / 100ml)
- Hloov los ntawm % daws rau molarity , muab cov % kev daws teeb meem los ntawm 10 los nthuav qhia cov feem pua tov grams/L, ces faib los ntawm cov mis hnyav.
Ntawm no, kuv yuav xam molarity li cas?
Rau xam molarity , faib tus naj npawb ntawm molesof solute los ntawm lub ntim ntawm cov tshuaj nyob rau hauv liters. Yog tias koj tsis paub tus naj npawb ntawm moles ntawm solute tab sis koj paub qhov loj, pib los ntawm kev nrhiav cov molar loj ntawm cov solute, uas yog sib npaug rau tag nrho cov moles ntawm txhua lub hauv paus hauv cov tshuaj ntxiv ua ke.
Ib yam li ntawd, koj ua li cas xam molarity ntawm normality? Yog koj paub cov Molarity ntawm ib qho acid lossis basesolution, koj tuaj yeem hloov tau yooj yim rau Zoo li qub bymultiplying Molarity los ntawm tus naj npawb ntawm hydrogen (orhydroxide) ions hauv cov kua qaub (los yog hauv paus). Rau piv txwv , 2 MH2SO4 tov yuav muaj ib Zoo li qub ntawm 4N (2 M x 2 hydrogenions).
Qhov thib ob, koj pom qhov feem pua ntawm kev daws teeb meem li cas?
Rau xam qhov loj feem pua los yog luj feem pua ntawm a daws , koj yuav tsum faib qhov loj ntawm lub solute los ntawm qhov loj ntawm lub daws (ob qho tib si cov kuab tshuaj thiab cov kuab tshuaj ua ke) thiab muab faib los ntawm 100 los hloov nws mus rau hauv feem pua.
Muaj pes tsawg moles nyob hauv HCl?
1 moles

Yuav ua li cas koj xam qhov zaus ntawm zaus thiab feem pua?
Ua li no, faib cov zaus los ntawm tag nrho cov txiaj ntsig thiab muab faib los ntawm 100. Hauv qhov no, qhov zaus ntawm thawj kab yog 1 thiab tag nrho cov txiaj ntsig yog 10. Qhov feem pua yog tom qab ntawd yog 10.0. Cov kab kawg yog qhov feem pua Cumulative
Koj yuav suav li cas feem pua ntawm cov tshuaj chlorine?
Cov tshuaj chlorine isotope nrog 18 neutrons muaj ntau ntawm 0.7577 thiab ib pawg ntawm 35 amu. Txhawm rau xam qhov nruab nrab atomic mass, muab cov feem los ntawm cov lej loj rau txhua tus isotope, tom qab ntawd ntxiv lawv ua ke
Yuav ua li cas koj thiaj nrhiav tau cov mis empirical nrog feem pua?
Transcript Faib txhua % los ntawm atomic mass ntawm lub caij. Faib txhua cov lus teb los ntawm qhov tsawg tshaj plaws. Kho cov lej no rau hauv lawv qhov qis tshaj tus lej tag nrho
Koj pom molarity li cas los ntawm qhov ntom thiab feem pua?
Molarity yog tus naj npawb ntawm moles ntawm soluteper liter ntawm kev daws. Hloov mus rau qhov ntom los ntawm kev muab cov lej ntawm moles los ntawm cov molecular loj ntawm cov compound.Hloov qhov ntom rau molarity los ntawm kev hloov mus rau gramsper liter thiab faib los ntawm molecular mass ntawm cov compound ingrams
Yuav ua li cas koj sau ib feem raws li ib tug khoom ntawm ib tug tag nrho cov zauv thiab ib feem feem?
Cov cai los nrhiav cov khoom ntawm ib feem feem thiab tag nrho tus lej Peb xub sau tag nrho cov lej ua ib feem, piv txwv li, sau nws faib los ntawm ib qho; Piv txwv li: 7 yog sau ua 71. Peb mam li muab cov zauv. Peb muab cov denominators. Yog tias yuav tsum tau ua kom yooj yim, nws ua tiav thiab tom qab ntawd peb sau cov feem kawg
