Qhov sib npaug yuav tsum yog y = mx + b daim ntawv. Yog li yog tias koj rho koj y-intercept los ntawm tus nqus tau thiab faib los ntawm txoj kab nqes, koj tab tom nrhiav qhov concentration ntawm koj tus qauv.
Ua li no, koj txiav txim siab molarity li cas?
Yog xam molarity , faib tus naj npawb ntawm moles ntawm 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 molar masses ntawm txhua lub caij hauv cov tshuaj ntxiv ua ke.
Tom qab, lo lus nug yog, dab tsi yog cov units ntawm absorbance? Absorbance yog ntsuas hauv absorbance units (Au), uas cuam tshuam rau kev xa tawm raws li pom hauv daim duab 1. Piv txwv li, ~ 1.0Au yog sib npaug rau 10% transmittance, ~ 2.0Au yog sib npaug rau 1% transmittance, thiab lwm yam nyob rau hauv ib tug logarithmic sib.
Tsis tas li ntawd, koj pom txoj kev ntev li cas hauv Beer txoj cai?
Ntawm no yog ib qho piv txwv ntawm kev siv ncaj qha Beer Txoj Cai Kev sib npaug (Absorbance = e L c) thaum koj tau txais cov molar absorptivity tas li (los yog molar extinction coefficient). Hauv qhov sib npaug no, e yog tus molar extinction coefficient. L yog txoj kev ntev ntawm tus tuav ntawm tes. c yog qhov concentration ntawm cov tshuaj.
A hauv Beer txoj cai yog dab tsi?
Kho tshiab Lub Kaum Ob Hlis 08, 2019. Beer Txoj Cai yog ib qho kev sib npaug uas cuam tshuam qhov attenuation ntawm lub teeb rau cov khoom ntawm cov khoom. Cov txoj cai hais tias qhov concentration ntawm cov tshuaj yog ncaj qha proportional rau lub absorbance ntawm ib tug tov.

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 pom qhov concentration ntawm DNA los ntawm absorbance?
DNA concentration yog kwv yees los ntawm kev ntsuas qhov nqus ntawm 260nm, kho qhov ntsuas A260 rau turbidity (tseem los ntawm absorbance ntawm 320nm), muab faib los ntawm cov khoom dilution, thiab siv kev sib raug zoo uas A260 ntawm 1.0 = 50µg / ml ntshiab dsDNA
Yuav ua li cas koj pom wavelength los ntawm absorbance?
Muab l los ntawm c thiab muab faib A los ntawm cov khoom los daws cov molar absorptivity. Piv txwv li: Siv lub cuvette nrog qhov ntev ntawm 1 cm, koj ntsuas qhov absorbance ntawm cov tshuaj nrog ib tug concentration ntawm 0.05 mol / L. Lub absorbance ntawm lub wavelength ntawm 280 nm yog 1.5
Koj yuav suav li cas feem pua molarity?
Moles thiab Molar dlaws (unit = M = moles / L) Percent Solutions (% = qhov chaw ib puas los yog grams / 100ml) Hloov los ntawm % tov rau molarity, muab cov % daws los ntawm 10 los qhia cov feem pua cov tshuaj grams / L, ces faib los ntawm tus qauv hnyav
Yuav ua li cas koj pom tus qauv enthalpy ntawm tsim los ntawm combustion?
Tus qauv enthalpy ntawm cov tshuaj tiv thaiv (Δ Horxn) tuaj yeem xam los ntawm cov lej ntawm cov qauv enthalpies ntawm kev tsim cov khoom (txhua qhov sib npaug los ntawm nws cov stoichiometric coefficient) rho tawm cov lej ntawm cov qauv enthalpies ntawm kev tsim cov reactants (txhua qhov sib npaug los ntawm nws. stoichiometric coefficient) - "cov khoom
