mol. Mole yog SI chav ntsuas ntawm kev ntsuas siv los ntsuas tus naj npawb ntawm cov khoom, feem ntau atoms lossis molecules. Ib mole ntawm ib yam dab tsi yuav muab 6.02214078 × 1023 ntawm tib yam (Avogadro tus lej).
Ib yam li ntawd, koj tuaj yeem nug, dab tsi yog mole hauv chemistry?
Cov mole yog tus nqi ntawm cov nqi hauv chemistry . A mole ntawm ib yam khoom yog txhais raws li: Qhov loj ntawm cov khoom uas muaj tib tus naj npawb ntawm cov hauv paus ntsiab lus raws li muaj atoms nyob rau hauv 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.
Ib yam li ntawd, qhov txawv ntawm mole thiab atom yog dab tsi? Mole yog tseg rau kev ntsuas me me xws li atoms los yog molecules. Atoms , ntawm qhov tod tes, yog qhov tsawg tshaj plaws pom tsis tau ntawm ib lub caij, uas yog qhov me me dhau los pom txawm tias lub tshuab tsom. Atoms muaj kev sib xyaw ua ke ntawm peb hom subatomic hais: protons, neutrons, thiab electrons.
Hauv qhov no, Mole yog dab tsi thiab nws chav nyob?
Mole ( chav tsev ) Cov mole (cim: mol ) yog chav tsev Kev ntsuas rau tus nqi ntawm cov khoom hauv International System ntawm Chav tsev (SI). Nws yog txhais raws nraim 6.02214076 × 1023 constitutive particles, uas tej zaum yuav yog atoms, molecules, ions, los yog electrons.
