Yog tias koj muaj kev daws teeb meem, koj muab cov molarity los ntawm qhov ntim hauv litres. Muaj ob kauj ruam: Muab lub ntim los ntawm qhov ceev kom tau qhov loj. Faib qhov loj los ntawm molar mass kom tau tus lej ntawm moles.
Tsis tas li ntawd, koj yuav hloov mus rau moles li cas?
Rau hloov grams rau moles , pib los ntawm kev muab cov lej ntawm cov atom los ntawm qhov hnyav atomic rau txhua lub caij hauv qhov sib xyaw. Tom qab ntawd, ntxiv tag nrho koj cov lus teb ua ke kom pom cov molar loj ntawm cov khoom sib xyaw. Thaum kawg, faib tus naj npawb ntawm grams ntawm cov compound los ntawm molar mass ntawm lub compound kom pom tus naj npawb ntawm moles.
Ib sab saum toj no, pes tsawg moles nyob hauv ib gram? Cov lus teb yog 0.0087094358027487 Peb xav tias koj tab tom hloov ntawm moles Hauv thiab gram. Koj tuaj yeem saib cov ntsiab lus ntxiv ntawm txhua chav ntsuas: molecular hnyav ntawm Hauv lossis grams Lub hauv paus SI rau cov khoom siv yog mole. 1 mole yog sib npaug 1 moles Hauv, los yog 114.818 grams.
Hauv qhov no, koj yuav ua li cas hloov mg / ml rau mol L?
NTAWM ( mg / ml TO molarity (M): Faib qhov concentration ( mg / ml ) los ntawm qhov hnyav molecular. Peb yuav siv cov piv txwv ntawm ib tug raug immunotoxin uas muaj ib tug molecular hnyav ntawm 210,000 grams ib. mole (los yog mg /mmole lossis kDa) (qhov hnyav molecular feem ntau pom muaj nyob rau ntawm daim ntawv teev cov ntaub ntawv) thiab cov concentration yog 1.0 mg / ml.
Muaj pes tsawg moles nyob rau hauv ib liter?
Kev sib npaug ntawm 1 mole = 22.4 L yog lub hauv paus rau kev hloov pauv.
Pom zoo:
Qhov piv ntawm moles ntawm dej rau moles ntawm CuSO4 yog dab tsi?
Faib tus naj npawb ntawm moles ntawm cov dej poob los ntawm tus naj npawb ntawm moles ntawm anhydrous ntsev kom tau qhov sib piv ntawm cov dej molecules rau cov qauv units. Hauv peb qhov piv txwv, 0.5 moles dej ÷ 0.1 moles tooj liab sulfate = 5: 1 ratio. Qhov no txhais tau tias rau txhua chav tsev ntawm CuSO4 tam sim no, peb muaj 5 molecules dej
Yuav ua li cas koj mus ntawm moles rau ntim?
Hloov los ntawm moles rau ntim (litres): Ua kom koj tus nqi mole los ntawm molar volumeconstant, 22.4L. Hloov los ntawm cov khoom (atoms, molecules, orformula units) rau moles: Faib koj cov nqi particle los ntawmAvogadro tus lej, 6.02 × 1023. Nco ntsoov siv cov kab lus ntawm koj lub laij lej
Nws puas yuav ua rau pom qhov sib npaug ntawm kab sib npaug mus rau ib kab thiab los ntawm ib qho taw tes ntawm kab?
Qhov sib npaug ntawm ib kab uas yog parallel lossis perpendicular rau ib kab? Cov lus teb tau: Cov nqes hav ntawm cov kab sib npaug sib npaug. Hloov txoj kab nqes paub thiab cov kev sib koom ua ke ntawm ib qho taw tes ntawm lwm txoj kab rau hauv daim ntawv point-slope kom pom qhov sib npaug ntawm kab sib npaug
Yuav ua li cas rau lub zog thaum koj tsiv mus rau lub pyramid?
Tus nqi ntawm lub zog ntawm txhua qib trophic txo qis thaum nws txav mus los ntawm ib qho ecosystem. Tsawg li 10 feem pua ntawm lub zog ntawm txhua qib trophic yog pauv mus rau qib tom ntej; tus so yog poob loj heev los ntawm cov txheej txheem metabolic li cua sov
Lub zog rau kev thauj mus los ntawm qhov twg thiab vim li cas thiaj li xav tau lub zog rau kev thauj mus los?
Kev thauj mus los nquag yog txheej txheem uas yuav tsum tau txav cov molecules tawm tsam qhov concentration gradient. Cov txheej txheem yuav tsum muaj zog. Lub zog rau cov txheej txheem tau txais los ntawm kev rhuav tshem cov piam thaj siv oxygen hauv kev ua pa aerobic. ATP yog tsim thaum ua pa thiab tso tawm lub zog rau kev thauj mus los
