pawg %C = ( pawg ua 1 mol carbon / pawg ua 1 mol CO 2) x 100. pawg %C = (12.01 g / 44.01 g) x 100. pawg %C = 27.29%
Ua raws li qhov xav tau, qhov feem pua ntawm cov pa roj carbon ntau hauv carbon monoxide yog dab tsi?
Ib feem pua ntawm cov khoom
| Element | Cim | Pawg Feem Xyuam |
|---|---|---|
| Cov pa roj carbon | C | 42.880% |
| Oxygen | O | 57.120% |
Kuj Paub, qhov loj feem pua ntawm cov pa oxygen hauv co2 yog dab tsi? %O = 32.00/44.01 = 0.7271 = 72.71 %O hauv CO2.
Hauv qhov no, pes tsawg feem pua ntawm cov pa roj carbon hauv carbon dioxide yog dab tsi?
Yog li, peb yuav muab 2 nrog 16.00 uas yog qhov hnyav ntawm cov pa. Qhov no yog tag nrho qhov hnyav ntawm CO2 . Tam sim no, kom paub feem pua muaj pes tsawg leeg ntawm Cov pa roj carbon thiab Oxygen. Peb yuav faib lawv qhov hnyav nrog tag nrho qhov hnyav ntawm CO2 . % C = 12.01/44.01 = 0.2729 = 27.29% (peb yuav faib 0.2729 nrog 100 coj feem pua.
Qhov feem pua ntawm cov pa oxygen hauv carbon monoxide yog dab tsi?
Gaseous muaj pes tsawg leeg ntawm huab cua qhuav.
| Cov ntsiab lus | Tshuaj cim | Mole feem pua |
|---|---|---|
| Nitrogen | N2 | 78.084 |
| Oxygen | O2 | 20.947 |
| Argon | Ar | 0.934 |
| Cov pa roj carbon dioxide | CO2 | 0.0350 |
