Peb kuj tuaj yeem siv moles los cuam tshuam rau qhov loj ntawm cov atoms , molecules . Yuav kom ua tau li ntawd, peb yuav tsum paub qhov loj ntawm cov molecule siv lub sij hawm ntev. Piv txwv li – qabzib (C6H12O6), ib hom suab thaj molecule, yog tsim los ntawm 6 carbon atoms , 12 hydrogen atoms ,,6 oxx atoms.
Tom qab ntawd, ib tug kuj yuav nug, pes tsawg carbon atoms muaj nyob rau hauv qabzib?
6 carbon atoms
Tom qab ntawd, lo lus nug yog, pes tsawg atoms ntawm carbon nyob rau hauv 9 g ntawm qabzib? Tam sim no rau 1 molecule ntawm qabzib , nyob ntawd yog 6 atom ntawm carbon (raws li los ntawm cov qauv molecular ntawm qabzib ) tam sim no hauv nws. Yog li tus naj npawb ntawm molecules ntawm carbon hauv molecules qabzib yuav tsum yog = atom ntawm carbon.
Tib neeg kuj nug, pes tsawg carbon atoms nyob rau hauv 18 grams qabzib?
Hauv 18g ib .. tsis muaj. ntawm carbon atoms luas = 0.6 × 6.022 × 10 ^ 23.. Yog li tus naj npawb ntawm molecules ntawm carbon nyob rau hauv 6.022∗1022 molecules ntawm qabzib yuav tsum = 6∗(6.022∗1022)=36.132∗1022 atom ntawm carbon.
Muaj pes tsawg carbon atoms rau peb molecules ntawm qabzib?
Ib molecule ntawm qabzib muaj 6 carbon atoms . Yog li yog tias koj muaj peb molecules ntawm qabzib , tsuas yog muab 3 los ntawm 6 carbon atoms . Lo lus teb raug yog C. 18 Cov pa roj carbon atoms.
