Dilute Solution ntawm Paub Molarity
Cov tshuab xam zauv siv tus qauv M1V1 = M2V2 qhov twg "1" sawv cev rau cov ntsiab lus tseem ceeb (piv txwv li kev daws teeb meem Molarity thiab ntim) thiab "2" sawv cev rau diluted tej yam kev mob (piv txwv li xav ntim thiab Molarity ).
Raws li, koj ua li cas xam cov concentration siv dilution factor?
Faib qhov ntim xav tau los ntawm dilution yam (400 ml / 8 = 50 ml) los txiav txim qhov ntim ntawm chav tsev. Cov dilution Tom qab ntawd ua raws li 50 ml tshuaj tua kab mob + 350 ml dej.
Tom qab, lo lus nug yog, dab tsi yog tus qauv rau kev suav dilution? Yuav ua kom tus nqi tas li ntawm a dilute kev daws teeb meem los ntawm kev daws teeb meem, koj tuaj yeem siv cov qauv : C1V1 = C2V2 qha: v1 = Qhov ntim ntawm cov khoom lag luam xav tau los ua cov tshuaj tshiab. C1 = Concentration of stock solution.
Raws li, koj ua li cas xam cov molarity ntawm cov tshuaj?
Yog xam molarity , faib tus naj npawb ntawm moles ntawm solute los ntawm lub ntim ntawm lub daws hauv litres. Yog tias koj tsis paub tus naj npawb ntawm moles ntawm solute tab sis koj paub qhov loj, pib los ntawm nrhiav molar mass ntawm lub solute, uas yog sib npaug rau tag nrho cov molar masses ntawm txhua yam nyob rau hauv lub daws ntxiv ua ke.
Dab tsi yog 1/10 dilution?
Piv txwv li, ua ib 1:10 dilution ntawm 1M NaCl tov, koj yuav sib tov ib "ib feem" ntawm 1M tov nrog cuaj "qhov" ntawm hnyav (tej zaum dej), rau tag nrho ntawm kaum "qhov." Yog li ntawd, 1:10 dilution txhais tau tias 1 feem + 9 feem ntawm dej (los yog lwm yam diluent).

Koj xam xam cov nyiaj hli sib kis li cas?
Rho tawm qhov tsawg kawg ntawm qhov siab tshaj plaws. Qhov no yog qhov ntau. Hauv qhov piv txwv, 500,000 rho 350,000 sib npaug 150,000. Faib qhov ntau los ntawm qhov tsawg kawg kom pom qhov sib kis
Koj xam xam qhov hnyav nruab nrab tus nqi ntawm cov khoom muag hauv Excel li cas?
Qhov Ntsuas Tus Nqi Nruab Nrab: Hauv txoj kev no, tus nqi nruab nrab ntawm ib chav tsev yog xam los ntawm kev faib tag nrho tus nqi ntawm cov khoom muag los ntawm tag nrho cov khoom muag. Xaus Cov Lus Nthuav Tawm tom qab ntawd xam los ntawm tus nqi nruab nrab ib chav los ntawm tus lej ntawm cov khoom muaj nyob rau thaum kawg ntawm lub sijhawm
Koj xam xam nyiaj hli tiag tiag li nyiaj hli thiab CPI li cas?
Qhov nruab nrab cov nyiaj ua haujlwm ib teev twg ntsuas hauv cov nyiaj tam sim no. Qhov nruab nrab cov nyiaj ua haujlwm ib teev ntsuas nyob rau hauv cov nyiaj tau los ntawm ib lub xyoo puag ncig. Tus nqi ua haujlwm tiag hauv xyoo 2002 = = $ 8.19 $ 14.76 180.3 x 100 Txhawm rau xam tus nqi ua haujlwm tiag, peb faib tus nqi ua haujlwm nominal los ntawm CPI thiab muab sib npaug 100
Koj xam xam tag nrho cov neeg yuav khoom li cas?
Hloov chaw, tag nrho cov kev yuav khoom yuav tsum raug xam los ntawm kev ntxiv cov khoom muag kawg rau tus nqi ntawm cov khoom muag thiab rho tawm cov khoom pib pib. Feem ntau cov tuam txhab yuav muaj cov ntaub ntawv khaws tseg ntawm kev yuav khoom, yog li qhov kev suav no yuav tsis xav tau
Yuav ua li cas koj ua ib tug dilution series?
Thawj kauj ruam hauv kev ua cov serial dilutionis coj lub ntim paub (feem ntau yog 1ml) ntawm cov khoom lag luam thiab muab tso rau hauv ib lub npe ntawm cov dej distilled (feem ntau 9ml). Qhov no ua rau 10 ml ntawm cov tshuaj dilute. Cov tshuaj dilute no muaj 1mlof extract / 10ml, ua 10-fold dilution
