Ib txoj hauv kev los piav txog qhov concentration ntawm kev daws yog los ntawm feem pua ntawm cov kuab tshuaj hauv cov kuab tshuaj Qhov feem pua ntawm cov kev txiav txim siab ntxiv tuaj yeem txiav txim siab hauv ob txoj hauv kev: (1) qhov ratio ntawm qhov loj ntawm lub solute muab faib los ntawm cov loj ntawm cov tshuaj los yog (2) qhov ratio ntawm lub ntim ntawm lub solute muab faib los ntawm lub ntim ntawm cov tshuaj.
Dab tsi yog qhov concentration ntawm 1% tov?
Ib ib feem pua txhais tau tias yog 1 gram ntawm cov kuab tshuaj rau 100 milliliters zaum kawg ntim. Piv txwv li, 1 gram ntawm sodium chloride, coj mus rau qhov kawg ntim ntawm 100 ml nrog dej distilled, yog 1% NaCl tov.
Dab tsi yog 5% concentration?
www.citycollegiate.com. 5% v / v tov txhais tau tias 5 ml of solute is dissolved 100 ml of solution.
Qhov concentration hauv feem pua txhais li cas?
Kev piav qhia: Feem ntau, thaum peb tham txog kev daws teeb meem hauv feem pua, peb txhais tau tias feem pua ntawm qhov hnyav, piv txwv li … Yog li 20⋅g ntawm cov kuab tshuaj hauv 80⋅g ntawm cov kuab tshuaj (uas feem ntau yog dej) muaj qhov concentration ntawm 20% (mm).
Puas yog concentration npaum li cas?
Molar concentration (tseem hu ua molarity, npaum li cas concentration lossis tshuaj concentration) yog ib qho kev ntsuas ntawm qhov concentration ntawm ib hom tshuaj, tshwj xeeb tshaj yog cov kua nyob rau hauv ib qho kev daws, hais txog tus nqi ntawm cov khoom hauv ib chav ntim ntawm cov tshuaj.
