A mole ntawm CuSO4•5H2O muaj 5 moles dej (uas sib haum rau 90 grams dej) ua ib feem ntawm nws cov qauv. Yog li, cov tshuaj CuSO4•5H2O ib txwm muaj 90/250 lossis 36% dej los ntawm qhov hnyav.

Ib yam li ntawd, koj tuaj yeem nug, ua li cas koj pom qhov loj feem pua ntawm cov dej hauv hydrate?

Faib cov pawg ntawm dej poob los ntawm pawg ntawm hydrate thiab muab faib los ntawm 100. Theoretical (qhov tseeb) feem pua hydration ( feem pua dej ) tuaj yeem yog xam los ntawm qauv ntawm hydrate los ntawm kev faib cov pawg ntawm dej nyob rau hauv ib tug mole hydrate ntawm molar pawg ntawm hydrate thiab muab faib los ntawm 100.

Tom qab ntawd, lo lus nug yog, qhov loj ntawm CuSO4 5h2o yog dab tsi? 159,609 g / mol

Raws li qhov no, qhov loj feem pua ntawm cov dej hauv tooj liab II sulfate hydrate yog dab tsi?

159.62 / 249.72 * 100 = 63.92 feem pua . Qhov no txhais tau tias 100-gram qauv ntawm tooj liab sulfate pentahydrate yuav muaj 63.92 grams tooj liab sulfate . Nws kuj txhais tau tias tooj liab sulfate pentahydrate 100 - 63.92 = 36.08 feem pua dej los ntawm pawg.

Vim li cas CuSO4 5h2o suav tias yog hydrate?

Yog vim li cas CuSO 4 . 5 h20 yog suav tias yog 'Hydrate ', los yog ntau dua yog 'pentahydrate' yog vim cov dej molecules uas tau muab tso rau hauv cov crsytals hauv hydrated daim ntawv.
