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 ua ), hnyav tawm 63.55 g tooj. 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.

Hauv qhov no, pes tsawg grams muaj nyob rau hauv 1 mole ntawm tooj liab atoms?

63,546g ua

Tsis tas li ntawd, lub mole ntawm tooj liab yog dab tsi? Los ntawm koj Lub Sijhawm Sijhawm peb kawm qhov ntawd mole ntawm tooj liab , 6.022 × 1023 ib tus neeg tooj liab atoms muaj qhov hnyav ntawm 63.55⋅g. Thiab yog li peb siv MASS ntawm cov qauv tshuaj los xam cov NUMBER ntawm atoms thiab molecules.

Tsis tas li ntawd, pes tsawg atoms muaj nyob rau hauv tooj liab?

Qhov loj ntawm 1 mole (6.022 x 1023 atoms ) tooj liab yog 63.55 g. Cov qauv peb tab tom txiav txim siab muaj qhov hnyav ntawm 3.14 g. Vim tias qhov hnyav tsawg dua 63.55 g, cov qauv no muaj tsawg dua 1 mole ntawm tooj liab atoms.

Muaj pes tsawg atoms nyob rau hauv 2 moles ntawm tooj liab?

Txhawm rau ua kom tiav qhov no, sib faib Avogadro tus lej - qhov kuv tau hais thaum pib ntawm qhov kev piav qhia no - los ntawm 2. Qhov no yuav muab koj cov naj npawb ntawm cov molecules hauv 2 moles ntawm ib yam khoom. Hauv lwm lo lus, 1 mole ntawm atoms yog 6.02 × 1023 atoms ua.
