Hloov los ntawm moles rau ntim (liter): Ua koj ntau mole tus nqi los ntawm molar ntim ua 22,4l. Hloov los ntawm cov khoom (atoms, molecules, orformula units) rau moles : Faib koj tus nqi particle los ntawmAvogadro tus lej, 6.02 × 1023. Nco ntsoov siv cov kab lus ntawm koj lub laij lej!
Ib yam li ntawd, koj puas tuaj yeem mus ntawm mL rau moles?
Multiply qhov ntom ntawm cov tshuaj (hauv units ntawm gramsper milliliter , los yog g/ mL ) los ntawm 1,000 mL (tus nqi ntawm milliliters nyob rau hauv 1 liter ntawm tov ntim). Faib qhov qub moles ntawm cov tshuaj nyob rau hauv 1 liter ntawm kev daws los ntawm theass ntawm tov nyob rau hauv kg.
Ib tug kuj nug, pes tsawg cm3 nyob rau hauv ib mole? ENDMEMO

Ib yam li ntawd, koj tuaj yeem nug, pes tsawg moles nyob hauv ib liter?
Kev hloov pauv ntawm Moles thiab Gas Volume. Molarvolume ntawm STP tuaj yeem siv los hloov los ntawm moles rau gasvolume thiab los ntawm cov roj ntim rau moles . Kev sib npaug ntawm 1 mole = 22.4 L yog lub hauv paus rau kev hloov pauv.
Muaj pes tsawg moles nyob rau hauv ib grams?
Koj tuaj yeem hloov pauv moles rau tus naj npawb ntawm particles ntawm ib yam khoom. Piv txwv li, peb pom tias 18 grams dej yog sib npaug rau 1 mole.

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 hloov lub ntim ntim hauv tsev muag tshuaj?
Kev hloov pauv ntawm cov tshuaj X yog 0.5mL / 40mg. Yog hais tias qhov xav tau concentration yog 4mg hauv 1mL, ces 20mL yog xav tau rau 80mg ntawm tshuaj X. Yog hais tias 40mg displaces 0.5mL ntawm cov tshuaj, nws txhais tau tias 80mg displaces 1mL. 20mL - 1mL = 19mL ntawm diluent xav tau
Koj mus ntawm ML mus rau moles li cas?
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 ntom kom tau qhov loj. Faib qhov loj los ntawm molar loj kom tau tus naj npawb ntawm moles
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
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
