Cov tshuaj chlorine isotope nrog 18 neutrons muaj ib kev nplua nuj ntawm 0.7577 thiab ib pawg loj ntawm 35 amu. Rau xam Qhov nruab nrab atomic loj, muab cov feem ntau los ntawm cov lej loj rau txhua tus isotope, tom qab ntawd ntxiv lawv ua ke.
Tom qab ntawd, ib tug kuj yuav nug, ua li cas koj xam cov feem pua abundance?
Nrhiav Qhov Nruab Nrab Atomic Mass ntawm ib lub ntsiab lus nrog Isotopes Muab txhua qhov isotope qhov loj los ntawm nws feem pua abundance . Ntxiv txhua yam khoom ntawm huab hwm coj lub sij hawm feem pua abundance ntawm txhua isotope. Cov nyiaj no sawv cev rau qhov hnyav nruab nrab atomic loj ntawm lub caij.
Tsis tas li ntawd, koj puas pom qhov nruab nrab atomic huab hwm coj los ntawm Percent abundance? Cov kev nplua nuj ntawm tag nrho cov isotopes yuav tsum ntxiv mus txog 100%. Multiply pawg lub sij hawm kev nplua nuj rau txhua tus isotope, tom qab ntawd ntxiv tag nrho cov txiaj ntsig ua ke kom tau txais nruab nrab atomic mass.
Kuj nug, qhov feem pua ntawm cov tshuaj chlorine 35 yog dab tsi?
Chlorine . ( tshuaj chlorine -37). Cov chlorine ntau - 35 yog 75% thiab cov chlorine ntau -37 yog 25%. Hauv lwm lo lus, hauv txhua 100 tshuaj chlorine atoms, 75 atoms muaj ib tug loj tus naj npawb ntawm 35 , thiab 25 atoms muaj cov lej ntawm 37.
Qhov feem pua kev nplua nuj txhais li cas?
Feem pua kev nplua nuj yog txhais raws li tus feem pua tus nqi ntawm qhov kom muaj nuj nqis ntawm isotopes muaj nyob rau hauv cov xwm rau ib tug muab lub caij.

Koj yuav daws li cas feem pua ntawm cov proportions?
Hauv kev faib ua feem ntawm cov khoom sib npaug sib npaug: Yog li 3 zaug 100 yog sib npaug rau 4 npaug ntawm PERCENT. Qhov ploj lawm PERCENT sib npaug 100 zaug 3 muab faib los ntawm 4
Yuav ua li cas koj sau ib feem raws li ib tug khoom ntawm ib tug tag nrho cov zauv thiab ib feem feem?
Cov cai los nrhiav cov khoom ntawm ib feem feem thiab tag nrho tus lej Peb xub sau tag nrho cov lej ua ib feem, piv txwv li, sau nws faib los ntawm ib qho; Piv txwv li: 7 yog sau ua 71. Peb mam li muab cov zauv. Peb muab cov denominators. Yog tias yuav tsum tau ua kom yooj yim, nws ua tiav thiab tom qab ntawd peb sau cov feem kawg
