Qhov txawv ntawm molarity thiab molality yog molarity yog cov moles ntawm cov kuab tshuaj tam sim no hauv 1 liter ntawm cov tshuaj whereas molality yog tus naj npawb ntawm moles ntawm solute tam sim no hauv 1kg ntawm cov kuab tshuaj.
Molarity thiab Mollality yog kev ntsuas ntawm cov kev daws teeb meem. Lub concentration ntawm ib qho kev daws muab cov nyiaj solutes yaj nyob rau hauv ib chav tsev nqi ntawm cov tshuaj. Qhov kev ntsuas ob yog sib txawv ntawm ib leeg raws li qhov ntsuas uas peb siv los ntsuas qhov ntsuas qhov ntsuas ntawm qhov ntsuas; molarity txiav txim siab qhov ntim ntawm cov tshuaj thaum molality txiav txim siab qhov loj ntawm cov kuab tshuaj. Txawm li cas los xij, nyob rau hauv ob qho tib si, peb ntsuas tus naj npawb ntawm cov kuab tshuaj hauv moles.
Molarity yog dab tsi?
Molarity yog qhov concentration ntawm cov tshuaj uas muab los ntawm tus lej ntawm cov kuab tshuaj tam sim no hauv ib liter ntawm kev daws. Yog li ntawd, peb ntsuas qhov concentration ntawm kev daws los ntawm kev ntim thaum txiav txim siab molarity. Chav ntsuas ntsuas yog mol / L.
Daim duab 01: Cov kev daws teeb meem sib txawv muaj qhov sib txawv nyob ntawm qhov ntim ntawm cov tshuaj
Tsis tas li ntawd, qhov ntsuas no nyob ntawm qhov ntsuas kub ntawm cov tshuaj vim tias qhov ntim ntawm cov tshuaj tuaj yeem sib txawv nrog qhov kub thiab txias, piv txwv li yuav luag txhua lub sijhawm cov kua ntim nrog qhov kub thiab txias. Piv txwv li, ib qho kev daws teeb meem uas muaj ob moles ntawm solute yaj hauv ib liter ntawm cov tshuaj muaj 2.0 mol / L concentration. Peb tuaj yeem qhia qhov molarity los ntawm "M".
Mollality yog dab tsi?
Molality yog qhov concentration ntawm cov tshuaj uas muab los ntawm tus nqi ntawm cov kuab tshuaj tam sim no hauv ib kilogram ntawm cov kuab tshuaj. Yog li ntawd, peb ntsuas qhov concentration ntawm ib qho kev daws los ntawm qhov loj ntawm cov kuab tshuaj thaum txiav txim siab molality ntawm cov tshuaj. Yog li, chav ntsuas ntsuas yog mol / kg.
Daim duab 02: Kev txiav txim siab ntawm Mollality ntawm kev daws
Ntxiv mus, qhov ntsuas no tsis nyob ntawm qhov ntsuas kub ntawm cov tshuaj vim tias qhov loj tsis hloov nrog qhov kub thiab txias. Piv txwv li, yog hais tias ib tug tov muaj 2 moles ntawm solutes yaj nyob rau hauv ib kilogram ntawm cov kuab tshuaj, ces cov concentration yog 2.0 mol / kg. Peb feem ntau txhais lo lus no ua "m".
Qhov txawv ntawm Molarity thiab Mollality yog dab tsi?
Molarity yog qhov concentration ntawm cov tshuaj uas tau muab los ntawm cov nyiaj solutes tam sim no nyob rau hauv ib liter ntawm kev daws whereas molality yog qhov concentration ntawm cov tshuaj muab los ntawm cov nyiaj solutes tam sim no nyob rau hauv ib kilogram ntawm hnyav. Yog li, qhov no yog qhov sib txawv tseem ceeb ntawm molarity thiab molality. Tsis tas li ntawd, qhov sib txawv tseem ceeb ntawm molarity thiab molality yog qhov molarity nyob ntawm qhov kub ntawm cov tshuaj thaum lub molality yog ywj siab ntawm qhov kub thiab txias. Qhov no feem ntau yog vim qhov ntim tuaj yeem nthuav dav nrog qhov kub thiab txias thaum qhov huab hwm coj tseem nyob tas li thaum hloov pauv kub.
Cov hauv qab no qhia qhov sib txawv ntawm molarity thiab molality hauv daim ntawv tabular.
Summary – Molarity vs Mollality
Molarity thiab Mollality yog kev ntsuas ntawm cov kev daws teeb meem. Qhov sib txawv tseem ceeb ntawm molarity thiab molality yog qhov molarity yog tus naj npawb ntawm moles ntawm cov kuab tshuaj tam sim no hauv 1 liter ntawm kev daws whereas molality yog tus naj npawb ntawm moles ntawm solute tam sim no hauv 1kg ntawm cov kuab tshuaj.
