Molarity (M) qhia tus naj npawb ntawm moles ntawm solute ib liter ntawm daws (moles / Liter) thiab yog ib qho ntawm feem ntau units siv los ntsuas qhov concentration ntawm a daws . Molarity siv tau los xam qhov ntim ntawm cov kuab tshuaj los yog tus nqi ntawm cov kuab tshuaj.
Ntawm no, koj nyeem molarity li cas?
Yuav xam cov molarity ntawm kev daws, koj faib cov moles ntawm solute los ntawm qhov ntim ntawm cov tshuaj qhia hauv litres. Nco ntsoov tias qhov ntim yog nyob rau hauv litres ntawm kev daws thiab tsis yog litres ntawm hnyav. Thaum a molarity yog qhia, chav tsev yog lub cim M thiab yog nyeem raws li "molar".
Ib yam li ntawd, molarity ntawm ib qho kev daws los ntawm kev sib cais yog dab tsi? Kev piav qhia: Molarity yog gm mole solute yaj ib liter ntawm hnyav. Txij li thaum 82.0343 gm sodium acetate hauv 1000 ml dej yog sib npaug rau 1 M molarity.
Yog li ntawd, vim li cas molarity tseem ceeb hauv chemistry?
Molarity yog tseem ceeb hauv chemistry vim, nws yog qhov ntsuas ntawm concentration. A molarity ntawm qhov kev daws teeb meem yog txoj hauv kev los txiav txim seb ntau npaum li cas ntawm cov khoom tshwj xeeb lossis cov khoom sib xyaw tau raug yaj lossis siv rau hauv qee qhov kev daws teeb meem. Molarity yog cov moles ntawm solute faib bu tus naj npawb ntawm liters ntawm ib tug tov.
Muaj pes tsawg moles nyob hauv NaOH?
1 moles

Vim li cas peb thiaj li hais txog kev txwv tsis pub muaj kev hais tawm thiab thaum twg peb yuav hais cov kev txwv?
Peb hais txog kev txwv vim nws yuav ua rau qhov sib npaug tsis tau txhais hauv qee qhov txiaj ntsig ntawm x. Qhov kev txwv ntau tshaj plaws rau cov lus qhia muaj nuj nqis yog N / 0. Qhov no txhais tau tias txhua tus lej muab faib los ntawm xoom tsis tau txhais. Piv txwv li, rau txoj haujlwm f(x) = 6/x², thaum koj hloov x = 0, nws yuav ua rau 6/0 uas tsis tau txhais
Cov kev tshawb fawb ntxaib thiab kev saws me nyuam qhia li cas rau peb txog kev txawj ntse?
Tsev Neeg, Ntxaib, Thiab Kev Kawm Txais yuav. Cov kev tshawb fawb caj ces muaj ib txwm siv cov qauv uas ntsuas qhov sib txawv ntawm IQ vim yog cov noob thiab ntau npaum li cas cuam tshuam nrog ib puag ncig. Cov kev tshawb fawb ntxaib no qhia tias qhov muaj txiaj ntsig (genetic effect) suav txog li ib nrab ntawm qhov sib txawv hauv 'g' cov qhab nia
Dab tsi yog qhov teeb meem loj tshaj plaws ntawm kev siv cov kev tshawb fawb txog kev sib raug zoo?
Tej yam tsis zoo los yog kev tshawb fawb txog kev sib raug zoo muaj xws li: a. Lawv tsis tuaj yeem siv los tsim kom muaj kev sib raug zoo-thiab-tshuaj los yog kev coj ntawm kev cuam tshuam
Vim li cas nws tseem ceeb uas peb txoj kev nkag siab txog kev tshawb fawb txog kev sib raug zoo txuas ntxiv mus?
Kev nthuav dav thiab kev loj hlob ntawm kev tshawb fawb txog kev sib raug zoo yog qhov tsim nyog vim nws pab txhawb koj txoj kev sib raug zoo thiab kev sib raug zoo nrog cov neeg hauv zej zog. Thaum koj nyob nrog cov neeg koj yuav tsum nkag siab lawv thiab social science pab koj ua li ntawd
Puas yog nws ua tau rau ib qho kev sib npaug ntawm ob txoj kab sib npaug kom tsis muaj kev daws teeb meem piav qhia koj qhov laj thawj?
Cov kab ke ntawm kab sib npaug tuaj yeem tsuas muaj 0, 1, lossis ib qho kev daws teeb meem tsis kawg. Ob kab no tsis tuaj yeem hla ob zaug. Cov lus teb raug yog tias qhov system muaj ib qho kev daws teeb meem.
