Cov ntsiab lus tseem ceeb

  1. 1 mole ntawm tej yam khoom muaj 6.022 × 1023 cov khoom .
  2. 6.022 × 1023 lub npe hu ua Avogadro Tus lej los yog Avogadro Constant thiab muab lub cim NA (1)
  3. N = n × NA N = tus naj npawb ntawm particle hauv cov khoom.
  4. Yuav nrhiav tau tus naj npawb ntawm particle , N, nyob rau hauv ib yam khoom:
  5. Yuav nrhiav tau tus nqi cov khoom hauv moles, n:

Ua raws li qhov no hauv kev txiav txim siab, koj ua li cas thiaj nrhiav tau tus lej ntawm cov khoom tawg?

Ntxiv los ntawm Avogadro's Tus lej Muab cov nqi tau txais hauv Kauj Ruam 3 los ntawm Avogadro's tus lej , uas sawv cev rau tus lej ntawm tus neeg sawv cev cov khoom hauv mole. Avogadro cov tus lej luas 6.02 x 10^23. Txuas ntxiv piv txwv, 2 moles dej x 6.02 x 10^23 cov khoom Luas = 1,20 x 10^24 cov khoom.

Ib sab saum toj no, pes tsawg tus hais txhais li cas? Cov particle naj npawb (los yog tus naj npawb ntawm particle ) ntawm cov txheej txheem thermodynamic, conventionally qhia nrog tsab ntawv N, yog tus lej ntawm qhov tsim nyog cov khoom hauv qhov system. Cov particle naj npawb yog ib qho tseem ceeb parameter hauv thermodynamics uas yog conjugate rau cov tshuaj muaj peev xwm.

Raws li txoj cai, koj yuav nrhiav tau pes tsawg tus hais hauv 1 mole?

Avogadro tus lej yog qhov tseem ceeb heev uas yuav tsum nco ntsoov: 1 mole = 6.022×1023 6.022 × 10 23 atoms , molecules , protons, thiab lwm yam. Yuav hloov los ntawm moles rau atoms , muab tus lej molar los ntawm Avogadro tus lej. Hloov los ntawm atoms rau moles , faib tus nqi atom los ntawm Avogadro tus naj npawb (los yog muab faib los ntawm nws cov reciprocal).

Muaj pes tsawg particles nyob rau hauv 3 moles?

Hauv chemistry thiab physics, Avogadro tas li yog tus naj npawb ntawm cov khoom siv cov khoom , feem ntau atoms los yog molecules , uas muaj nyob rau hauv tus nqi ntawm cov khoom muab los ntawm ib tug mole luas 6.02 x 10*23. Yog li 3 moj ntawm carbon atoms Luas = 18.06 x 10 * 23.
