Teb thiab piav qhia:
Cov molar mass ntawm Al (NO3) 3 yog 212.996238 g/mol. Peb tuaj yeem txiav txim siab qhov molar loj ntawm aluminium nitrate los ntawm kev ntxiv cov molar loj ntawm aluminium mus rau
Kuj nug, dab tsi yog qhov molar loj ntawm txhuas nitrate?
212,996 g / mol
Tom qab, lo lus nug yog, koj ua li cas txiav txim siab molar mass? Ntsiab Lus
- Cov molar loj yog qhov loj ntawm cov khoom siv tshuaj lossis tshuaj lom neeg (g) faib los ntawm cov khoom (mol).
- Cov molar loj ntawm ib qho compound tuaj yeem suav tau los ntawm kev ntxiv cov qauv atomic masses (hauv g / mol) ntawm cov khoom siv atom.
Hais txog qhov no, molar pawg ntawm Al c2h3o2 3 yog dab tsi?
Yog li, tag nrho pawg 177 + 59 = 236 g / mol.
Dab tsi yog aluminium nitrate siv rau?
Siv . Aluminium nitrate yog ib tug muaj zog oxidizing neeg sawv cev. Nws yog siv hauv tanning tawv, antiperspirants, corrosion inhibitors, extraction ntawm uranium, roj refining, thiab raws li ib tug nitrating neeg sawv cev. Cov nonahydrate thiab lwm yam hydrated aluminium nitrates muaj ntau daim ntawv thov.
