Molarity (M) qhia tus naj npawb ntawm moles ntawm cov kuab ib liter ntawm daws (moles / Liter) thiab yog ib qho ntawm feem ntau units siv ntsuas qhov concentration ntawm kev daws . Molarity siv tau xam qhov ntim ntawm cov kuab tshuaj los yog tus nqi ntawm cov kuab tshuaj.

Nyob rau hauv kev hwm rau qhov no, qhov twg yog qhov zoo tshaj plaws los qhia txog qhov concentration ntawm cov tshuaj?

Nws tuaj yeem hais tau ntau yam txoj kev : molarity (moles ntawm solute ib liter ntawm daws ); mole feem, qhov piv ntawm tus naj npawb ntawm moles ntawm solute rau tag nrho cov moles ntawm cov khoom tam sim no; mass feem pua, qhov ratio ntawm qhov loj ntawm lub solute mus rau qhov loj ntawm lub daws x 100; ib txhiab (ppt), grams

Dab tsi yog peb txoj hauv kev kom muaj nuj nqis ntawm kev qhia txog kev daws teeb meem? Muaj nuj nqis units ntawm concentration suav nrog molarity, molality, huab hwm coj feem pua, qhov chaw ib txhiab, qhov chaw ib lab, thiab ib feem ntawm billion.

Kuj nug, cov nqe lus twg tuaj yeem siv los nthuav qhia qhov concentration ntawm kev daws teeb meem?

Molarity (M) Yog tias qhov hnyav lossis ntim ntawm cov kuab tshuaj tau teev tseg, qhov no txhais tau tias koj xav tau cov kuab tshuaj ua ntej cov kuab tshuaj ntxiv. Molarity feem ntau yog feem ntau siv txoj kev ntsuas concentration thiab txhais tau tias yog tus naj npawb ntawm moles ntawm solute ib liters ntawm daws.

Qhov concentration ntawm kev daws yog dab tsi?

Cov concentration ntawm ib yam khoom yog qhov kom muaj nuj nqis ntawm solute tam sim no nyob rau hauv ib tug muab kom muaj nuj nqis daws . Kev xav feem ntau yog qhia nyob rau hauv cov nqe lus ntawm molarity, txhais raws li tus naj npawb ntawm moles ntawm solute nyob rau hauv 1 L ntawm daws.
