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.

Yog li ntawd, pes tsawg atoms nyob rau hauv ib mole ntawm tooj liab?

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.

Tom qab ntawd, lo lus nug yog, pes tsawg grams muaj nyob rau hauv 1 mole ntawm tooj liab atoms? 63,546g ua

Ib yam li ntawd, qhov loj ntawm 3.5 moles ntawm tooj liab yog dab tsi?

Teb thiab piav qhia: Pawg ntawm Cu hauv grams tuaj yeem muab tau los ntawm kev sib npaug ntawm pawg hauv amu nrog Avogadro tus lej. Yog li ntawd, lub qhov hnyav ntawm 3.5 moles Cu yog 3.69 × 10-22 grams 3.69 × 10 - 22 grams.

Dab tsi yog mole hauv science?

Mole , kuj spelled mol, hauv chemistry, tus qauv kev tshawb fawb chav ntsuas ntsuas qhov loj ntawm cov khoom me me xws li atoms, molecules, lossis lwm yam hais.
