Ib mole atoms ntawm oxygen muaj ib pawg ntawm 16 g , raws li 16 yog qhov hnyav ntawm atomic oxygen , thiab muaj 6.02 X 1023 atoms ntawm oxygen.
Tom qab ntawd, ib tug kuj yuav nug, dab tsi yog qhov loj hauv grams ntawm 6.022 x10 23 molecules dej?
Skill 3-1 Xam cov molecular pawg ntawm ib tug compound raws li qhov sum ntawm cov atomic masses ntawm nws cov ntsiab. Yog li ntawd, ib tug mole dej ( 6.022 x 10 23 molecules ) muaj a pawg ntawm 18.02 g.
Ib yam li ntawd, qhov loj ntawm 2.23 x 10 23 atoms ntawm sulfur yog dab tsi? Lub atomic pawg ntawm leej faj yog 32.07 g/mole. Yog li; 2.23 × 10 23 atom ua = ?
Tom qab ntawd, lo lus nug yog, dab tsi yog qhov loj ntawm Avogadro cov pa oxygen molecules?
Muaj ib qho kev sib raug zoo ntawm molar mass thiab atomic hnyav: Oxygen lub atomic hnyav yog 16.00 amu. 1 mole ntawm oxygen yog 6.02 x 1023 atoms ntawm oxygen 1 awm = 1.661 x 10-24g Qhov molar mass (g/mole) ntawm oxygen yog dab tsi? Molar mass (hauv grams) yeej ib txwm sib npaug rau qhov hnyav ntawm lub atom!
Qhov loj hauv grams ntawm 6.022 x10 23 molecules ntawm co2 yog dab tsi?
Teb thiab piav qhia: Lub pawg ntawm ib tug mole CO2 yog 44.01 grams . Muaj 6.022 X 1023 molecules ntawm CO2 nyob rau hauv ib tug mole, txaus los ua tus grams nyob rau hauv lub mole sib npaug pawg
Pom zoo:
Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Qhov txawv ntawm qhov loj ntawm ib tug proton thiab qhov loj ntawm ib tug electron yog dab tsi?
Protons thiab neutrons muaj kwv yees li qub, tab sis lawv yog ob qho tib si loj dua li cov hluav taws xob (kwv yees li 2,000 npaug loj li electron). Tus nqi zoo ntawm ib qho proton yog sib npaug hauv qhov loj rau qhov tsis zoo ntawm tus electron
Dab tsi yog qhov yuam kev loj tshaj plaws yog tias Irina ntsuas qhov ntev ntawm nws lub qhov rais li 3.35 feet qhov yuam kev loj tshaj plaws yog taw?
Kev daws: Qhov yuam kev loj tshaj plaws hauv kev ntsuas ntsuas tau txhais tias yog ib nrab ntawm qhov ntsuas ntsuas
Dab tsi yog qhov pom huab loj loj ntawm cov pa roj thiab plua plav hauv qhov chaw nruab hnub?
Qhov no nebula ( huab cua thiab plua plav hauv qhov chaw ) yog lub hnub qub ci ntsa iab. Lub Spitzer Space Telescope coj daim duab no nyob rau hauv lub teeb infrared, uas ci los ntawm huab cua plua plav kom pom cov hnub qub tshiab tau yug hauv nws. Star-forming Fingers: Cov huab zoo nkauj, ci ntsa iab ntawm plua plav no hu ua Eta Carinae Nebula
