Yog li ntawd, 4 moj ntawm dej yuav muaj 4 (6.022x10^23) cov dej molecules.

Kuj paub, muaj pes tsawg tus dej molecules nyob rau hauv 2 moles dej?

1 mole = 6.022×10^23 atoms . 1 dej molecule = 2 Hydrogen atoms + 1 oxygen atom. Yog li ntawd, 1 luj H2O = 1.2044 × 10^24 hydrogen atoms . Yog li ntawd 2 mole H2O yuav muaj 2.4088 × 10^24 hydrogen atoms.

Ib tug kuj yuav nug, pes tsawg molecules nyob rau hauv 1 mole ntawm molecules? Hauv chemistry, a mole yog ib chav tsev kom muaj nuj nqis uas sawv cev rau tus nqi ntawm cov khoom muab. Txij thaum ib mole ntawm ib qho tshuaj compound ib txwm muaj 6.022 x 10^23 molecules , koj tuaj yeem xam tus naj npawb ntawm molecules ntawm tej yam khoom yog tias koj paub nws cov huab hwm coj thiab nws cov tshuaj formula.

Kuj Paub, muaj pes tsawg tus dej molecules nyob rau hauv 6 moles?

Ceev Mole Xyuas Tus lej 6.022 x 1023 yog lub npe hu ua Avogadro's Number. Ib mole ntawm carbon-12 atoms muaj 6.022 x 1023 carbon-12 atoms. Ib lub txiv apples muaj 6.022 x 1023 txiv apples. Ib tug mole ntawm dej muaj 6.022 x 1023 dej molecules.

Muaj pes tsawg grams hauv 4 moles dej?

Nws yog sib npaug rau Avogadro tus lej (NA), uas yog 6.022 x1023. Yog hais tias peb muaj ib tug mole ntawm dej, ces peb paub hais tias nws yuav muaj ib tug loj ntawm 2g ua (rau 2 moles ntawm H atoms) + 16 grams (rau ib mole O atom) = 18g ua.
