Elemental muaj pes tsawg leeg ntawm CaCO3 * 3Ca3 (PO4) 2
| Element | Cim | Pawg feem pua |
|---|---|---|
| Calcium | Ca | 38.8874 |
| Cov pa roj carbon | C | 1.1654 |
| Oxygen | O | 41.9151 |
| Phosphorus | P | 18.0322 |
Ntawm no, pes tsawg feem pua ntawm cov pa muaj nyob hauv cov compound CaCO3 3ca3 po4 2?
3ca 3 ( PO 4 ) 2 . (a) 23.3%
Tsis tas li ntawd, qhov molecular loj ntawm CaCO3 yog dab tsi? 100.0869 g / mol
Tsis tas li ntawd, qhov feem pua ntawm cov pa oxygen hauv CaCO3 yog dab tsi?
Calcium Carbonate ( CaCO 3 ) muaj 40% calcium, 12% carbon thiab 48% oxygen los ntawm pawg.
Qhov formula rau Percent Composition yog dab tsi?
Qhov sib npaug ntawm qhov feem pua ntawm qhov sib xyaw yog ( pawg ntawm lub ntsiab / molecular loj ) x 100. Nrhiav cov molar loj ntawm tag nrho cov ntsiab lus nyob rau hauv compound nyob rau hauv grams ib mole.

Qhov feem pua ntawm qhov loj ntawm BR hauv CuBr2 yog dab tsi?
Cov feem pua ntawm cov ntsiab lus Element Symbol Mass Percent Copper Cu 28.451% Bromine Br 71.549%
Dab tsi yog qhov feem pua enantiomeric tshaj ntawm qhov sib tov uas muaj 86?
Enantiomeric tshaj (ee): Qhov ntau tshaj ntawm ib qho enantiomer tshaj qhov sib tov ntawm enantiomers. Qhia lej: enantiomeric tshaj = % ntawm cov enantiomer loj - % ntawm cov me me enantiomer. Piv txwv li: Ib qho kev sib xyaw ua ke ntawm 86% R enantiomer thiab 14% S enantiomer muaj 86% - 14% = 72% ee
