Unit mole ” yog siv nyob rau hauv chemistry raws li ib tug suav unit rau ntsuas tus nqi ntawm ib yam dab tsi. Ib mole ntawm ib yam dab tsi muaj 6.02 × 1023 units ntawm qhov ntawd. Qhov loj ntawm tus lej 6.02 × 1023 yog qhov nyuaj rau kev xav. Lub hom phiaj ntawm qhov no qhov project yog to taub xwb loj npaum li cas a mole yog.

Ib yam li ntawd, loj npaum li cas yog mole chemistry piv txwv?

Vim lub mole muaj ntau units, lawv feem ntau siv nyob rau hauv chemistry yog ib txoj hauv kev los ntsuas cov khoom me me xws li atoms lossis molecules. Yog li ntawd a mole dej yog 6.02 x 10²³ molecules dej, uas ua hauj lwm tawm li 18 grams, los yog 18 mL. A mole ntawm aluminium yog li 26 grams.

Qhov thib ob, chemistry txhais li cas mole? Cov mole yog unit ntawm tus nqi nyob rau hauv chemistry . A mole ntawm ib yam khoom yog txhais xws li: Qhov loj ntawm cov khoom uas muaj tib tus naj npawb ntawm cov hauv paus ntsiab lus raws li muaj yog atoms raws nraim 12.000 g ntawm ¹²C. Cov chav hauv paus tej zaum yuav yog atoms, molecules, los yog formula units, nyob ntawm seb cov khoom muaj feem xyuam.

Qhov thib ob, qhov kev ua ntawm mole loj npaum li cas?

A mole yog ib lo lus siv los txheeb xyuas qhov muaj nuj nqis, 6.02 x 1023 daim (tseem hu ua Avogadro tus lej).

Tus qauv ntawm mole tswvyim yog dab tsi?

Tus naj npawb ntawm moles nyob rau hauv ib qho piv txwv ntawm ib lub ntsiab / compound yuav xam tau los ntawm kev faib tag nrho pawg ntawm tus qauv los ntawm molar loj ntawm lub ntsiab / compound, raws li tau piav los ntawm cov nram qab no qauv . Yog li ntawd, qhov loj ntawm ib mole ntawm ib lub caij yuav muab sib npaug rau nws cov atomic loj hauv grams.
