Teb thiab piav qhia:
Muaj 24 atoms nyob rau hauv ib lub molecule ntawm C6 H12 06. Cov tshuaj no muaj 6 atoms carbon, 12 atoms hydrogen, thiab 6 atoms ntawm oxygen.
Yog li ntawd, tag nrho cov atoms hauv.260 mol qabzib yog dab tsi?
Muaj 12 hydrogen atoms nyob rau hauv 1 molecule qabzib , muaj Avogadro'a tus lej 6,02 x 10^23, atoms hauv ib mole ntawm tej yam khoom. Yog li ntawd yuav muaj: 1.32 x 12 x 6.02 x 10^23 = 9.54 x 10^24 hydrogen atoms ua 1,32 moles ntawm qabzib . Vam tias qhov no yuav pab tau.
Tsis tas li ntawd, muaj pes tsawg atoms nyob hauv qabzib? 1 molecule ntawm qabzib muaj 6 atom ua ntawm C, 12 atom ua ntawm H, thiab 6 atom ua ntawm O • 1 mole ntawm qabzib muaj 6 moles ntawm C atoms, 12 moles ntawm H atoms, thiab 6 moles ntawm O atoms.
Tsis tas li ntawd, muaj pes tsawg lub ntsiab lus sib txawv hauv c6h12o6?
peb yam sib txawv
Dab tsi yog tag nrho cov pa oxygen atoms hauv ib lub molecule ntawm qabzib c6h12o6?
