Phosphorus pentoxide yog cov tshuaj lom neeg nrog cov mis molecular P₄O₁₀. Cov dawb crystalline khoom no yog cov anhydride ntawm phosphoric acid. Nws yog lub zog desiccant thiab lub cev qhuav dej.
Yuav ua li cas yog molar pawg ntawm cov tshuaj hauv qab no diphosphorus pentoxide?
Yog li, molar pawg ntawm diphosphorus pentoxide yog M(P4O10)=30.973762(4) + 15.999(10.)= 283.886 g/mol.
Vim li cas P2O5 tsis yog diphosphorus pentoxide?
Lub npe lub npe txawm li cas los xij tau muab los ntawm nws empirical qauv, tsis yog los ntawm nws cov mis molecular. Tus qauv lub npe rau cov tshuaj no yog diphosphorus pentoxide. Lub di-prefix yog siv los qhia tias cov compound muaj ob phosphorus atoms thiab penta-prefix yog siv los qhia tias nws muaj tsib oxygen atoms.
Koj pom cov molar loj ntawm P2O5 li cas?
teb
- P2O5 yog lub npe hu ua Phosphorus Pentoxide.
- Calculation:-
- (molar mass of phosphorus)2 + (molar mass of oxygen)5.
- (30.9738)2 + (15.9994)5.
Muaj pes tsawg moles nyob hauv diphosphorus pentoxide?
2 Teb Los Ntawm Cov Kws Qhia Ntawv. Txhua molecule ntawm Diphosphours Pentoxide muaj 5 ntawm oxygen atoms (cov ntawv sau npe). Qhov ntawd txhais tau hais tias ib mole ntawm Diphosphorus Pentoxide yuav muaj tsib moles ntawm oxygen atoms.
