Kev txhais ntawm molarity: Molarity (M), lossis molar concentration, yog qhov concentration ntawm cov tshuaj ntsuas raws li tus naj npawb ntawm moles ntawm solute ib liter ntawm kev daws. Piv txwv li, 6 M HCl tov muaj 6 moles ntawm HCl ib liter ntawm cov tshuaj.
koj txhais li cas ntawm molarity?
Molarity (M) yog tus nqi ntawm cov khoom hauv ib lub ntim ntawm cov tshuaj. Molarity yog txhais raws li cov moles ntawm ib tug solute ib liter ntawm ib tug tov. Molarity tseem hu ua molar concentration ntawm cov tshuaj.
molarity thiab piv txwv yog dab tsi?
Kev piav qhia: Kom tau txais cov molarity, koj faib cov moles ntawm cov kuab tshuaj los ntawm litres ntawm cov tshuaj. Molarity=moles of solutelitres of solution. Piv txwv li, 0.25 mol / L NaOH tov muaj 0.25 mol ntawm sodium hydroxide nyob rau hauv txhua liter ntawm tov.
Dab tsi yog txhais thiab units ntawm molarity?
Molarity (M) qhia tus naj npawb ntawm moles ntawm cov ntsiab lus ib liter ntawm cov tshuaj (moles / Liter) thiab yog ib qho ntawm cov feem ntau siv los ntsuas qhov concentration ntawm ib daws. Molarity yuav siv tau los xam qhov ntim ntawm cov kuab tshuaj los yog tus nqi ntawm solute.
molarity sau formula yog dab tsi?
Nyob hauv chemistry, qhov concentration ntawm cov tshuaj feem ntau yog ntsuas hauv molarity (M), uas yog tus naj npawb ntawm moles ntawm cov kuab tshuaj ib liter ntawm kev daws. Qhov no molar concentration (ci) yog xam los ntawm kev faib cov moles ntawm solute (ni) los ntawm tag nrho cov ntim (V)of the: ci=niV . SI unit rau molar concentration yog mol/m3.
