Molarity yog tus naj npawb ntawm moles ib chav tsev ntim ntawm qhov daws thiab molality yog tus naj npawb ntawm moles ib chav tsev loj ntawm cov kuab tshuaj. Volume yog qhov kub thiab txias nyob qhov twg raws li huab hwm coj yog tas li ntawm txhua qhov kub. Yog li ntawd, molality tseem nyob tas li tab sis molarity hloov nrog kub. Yog li ntawd, molality yog nyiam dua molarity.

Hais txog qhov no, dab tsi yog qhov txiaj ntsig tseem ceeb ntawm Mollality tshaj molarity raws li chav nyob ntawm concentration?

Ob leeg yog siv los xam tus naj npawb ntawm moles ntawm solute. Tab sis los ntawm kev siv molality lub sij hawm peb tuaj yeem xam cov moles ntawm cov kuab tshuaj hauv cov kuab tshuaj, yog li nws muab cov qhov zoo ntawm kev paub tus naj npawb ntawm moles ntawm solute hauv hnyav thaum nyob rau hauv molarity Peb tsuas tuaj yeem suav tus lej ntawm cov moles ntawm cov kua hauv cov kua (ib litre).

Tsis tas li ntawd, qhov twg yog qhov zoo dua molarity lossis molality? Mollality raug txiav txim siab zoo dua rau kev nthuav qhia cov concentration piv rau molarity vim cov molarity hloov nrog qhov kub thiab txias vim qhov nthuav dav lossis kev cog lus ntawm cov kua nrog qhov kub thiab txias.

Tsis tas li ntawd, yog vim li cas molality thiab tsis molarity siv nyob rau hauv qhov kev qhia ntawm qhov chaw khov kho kev nyuaj siab?

Colligative zog yog lub cev ntawm kev daws teeb meem, zoo li boiling taw tes elevation thiab freezing point kev nyuaj siab . Qhov no yog vim li cas peb siv molality (moles solute ib kg ntawm hnyav) txij li thaum kg ntawm hnyav tsis hloov nrog kub.

Vim li cas peb thiaj siv Mollality?

Concentrations qhia nyob rau hauv molality yog siv thaum kawm cov khoom ntawm kev daws teeb meem ntsig txog vapor siab thiab kub hloov pauv. Mollality yog siv vim nws tus nqi tsis hloov nrog kev hloov pauv ntawm qhov kub thiab txias. Qhov ntim ntawm kev daws, ntawm qhov tod tes, yog me ntsis nyob ntawm qhov kub thiab txias.
