Cov mole thiab Avogadro tus lej. Ib mole ntawm ib yam khoom yog sib npaug rau 6.022 × 10²³ units ntawm cov khoom (xws li atoms, molecules, los yog ions ).

Ib yam li ntawd, tib neeg nug, moles ntawm ions txhais li cas?

Molar Concentration ntawm Ions Piv txwv qhov teeb meem Molarity yog ib tug concentration nyob rau hauv cov nqe lus ntawm moles ib liter ntawm kev daws. Vim ib ionic compound dissociates rau hauv nws cov Cheebtsam cations thiab anions insolution, tus yuam sij rau qhov teeb meem yog txheeb xyuas ntau npaum li cas moles ntawm ions yog ua thaum lub sij hawm dissolution.

Tom qab ntawd, lo lus nug yog, pes tsawg ions nyob hauv CaCl2? Hauv CaCl 2 , cov tshuaj formula qhia peb tias muaj ob moles ntawm Cl1- nyob rau hauv txhua mole ntawm compound, thiab peb moles ntawm tag nrho ions (1 mole Ca2+, 2 moles Cl1-) nyob rau hauv txhua mole ntawm compound.

Ntawm no, koj yuav ua li cas nrhiav tau tus naj npawb ntawm ions hauv kev daws teeb meem?

Yog li 1 mole ntawm NaCl hnyav 58.5g. Yog li tam sim no peb xav hloov cov grams rau hauv moles los ntawm kev faib pawg hauv grams los ntawm qhov loj ntawm 1mole. Qhov no txhais tau tias hauv 1dm3 ntawm daws yuav tsum muaj 1 mole ntawm sodium ions . Cov tus lej ntawm cov khoom hauv 1mole yog muab los ntawm Avogadro Constant uas yog sib npaug rau 6.02x1023mol−1.

Muaj pes tsawg chloride ions nyob rau hauv 2 mol ntawm CaCl2?

1 mole ntawm CaCl2 muaj 1 mole Ca2+ thiab 2 mool Cl- ua. Yog 1 mole Cl- yog 6.02x1023 Cl- ions , tiam 1 mole ntawm CaCl2 muaj( 2 x 6.02 x 1023) Cl– ions los yog 1.20 x 1024Cl– ions.
