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.
Pom zoo:
Muaj pes tsawg moles ntawm oxygen atoms nyob rau hauv ib mole ntawm Al2O3?
(c) 1 molecule ntawm Al2O3 muaj 3 atoms ntawm oxygen. Yog li, 1 mole ntawm Al2O3 muaj
Muaj pes tsawg atoms nyob rau hauv 1 mole ntawm tooj liab?
Lub tswv yim 2. Kev sib raug zoo ntawm molecular (formula) mass thiab molar mass Page 4 4 • Kom tau ib mole ntawm tooj liab atoms (6.02 x 1023 atoms), hnyav 63.55 g tooj liab. Molar mass (M) ntawm ib yam khoom yog qhov loj ntawm ib qho mole ntawm cov chaw (atoms, molecules, lossis formula units) ntawm cov khoom
Muaj pes tsawg atoms nyob rau hauv ib gram ntawm uranium?
Yeej koj faib Avogadro tas li los ntawm atomic loj ntawm lub caij mus nrhiav tus naj npawb ntawm cov atoms ntawm lub caij hauv ib gram. Yog li Uranium-235 muaj 6.02214179 × 1023 / 235 = 2.5626135 × 1021 atoms ib gram
Muaj pes tsawg atoms nyob rau hauv 2 moles ntawm co2?
Tus naj npawb ntawm cov chaw hauv ib mole yog muab los ntawm Avogadro tas li, NA, uas yog kwv yees li 6.022 × 1023 qhov chaw ib mol. Rau CO2 qhov chaw yog molecule ua los ntawm 3 atoms. Yog li hauv 2 moles peb muaj nyob ib ncig ntawm, 2mol × 6.022 × 1023 molecules mol− 1, uas yog 1.2044 × 1024 molecules
Muaj pes tsawg atoms nyob rau hauv ib mole ntawm argon?
7.66 X 10^5 millimols Argon (1 moleargon / 1000mmol) (6.022 X 10^23 / 1 mole Ar) = 4.61 X 10^25 atomsof
