Avogadro tus lej qhia peb tias muaj 6.022 x 10^23 molecules ntawm CO2 hauv 1 mole ntawm cov pa. Yog li ntawd, muaj 6.022 x 10^23 atoms ntawm carbon thiab 12.044 x 10^23 atoms ntawm oxygen hauv 1 mole ntawm CO2.

Ib yam li ntawd, pes tsawg atoms muaj nyob rau hauv 1 mole ntawm co2?

A mole ntawm CO2 molecules (peb feem ntau tsuas yog hais tias a mole ntawm CO2 ”) muaj ib mole ntawm carbon atoms thiab ob moles ntawm oxygen atoms . Lub atom piv thiab cov mole piv ntawm tus cov ntsiab lus zoo ib yam! 1 -). Txhua nitrate ion muaj ib tug nitrogen atom thiab peb cov pa oxygen atoms.

Kuj Paub, pes tsawg moles ntawm C nyob hauv co2? Qhov hnyav ntawm CO2 yog 44g mole (1 x 12 gramm) mole rau cov carbon thiab 2 x 16 grams / mole rau cov pa oxygen atoms).

Ntxiv mus, pes tsawg atoms ntawm carbon thiab oxygen muaj nyob rau hauv 1.5 mole ntawm co2?

muaj ib tug carbon atom thiab muaj ob oxygen atoms. Yog li, nyob rau hauv tag nrho muaj peb atoms . atoms. Yog li, suav cov atoms hauv 1.5 mole raws li hauv qab no.

Muaj pes tsawg atoms ntawm oxygen nyob rau hauv 6.93 moles ntawm co2?

1 lwg mol CO2 = 1 C atom + 2 O atom. Yog li ntawd, 3 moles ntawm CO2 muaj (3 x 2 x 6.02 x 10 * 23) O atoms Luas = 3,61 x 10 x 24 O atoms.
