Peb xav tias koj tab tom hloov ntawm moles SO2 thiab gram. Koj tuaj yeem saib cov ntsiab lus ntxiv ntawm txhua chav ntsuas: molecular hnyav ntawm SO2 lossis grams Cov tshuaj no tseem hu ua SulfurDioxide. SI base unit rau tus nqi ntawm cov khoom yog mole. 1 mole yog sib npaug 1 moles SO2, sau 64.0638 grams.

Tsis tas li ntawd, muaj pes tsawg tus hais nyob rau hauv 2 moles ntawm so2?

Yog li 1 mol SO2 yuav muaj 6.022 x 1023 molecules ntawm SO2 . 2 . Txhua SO2 moleculecontains 2 atom ua ntawm oxygen.

Tsis tas li ntawd, kuv yuav xam moles li cas? Siv cov qauv molecular rau nrhiav cov molar loj; kom tau tus naj npawb ntawm moles , faib qhov loj ntawm compound los ntawm molar loj ntawm lub compound qhia nyob rau hauv grams.

Tseem yuav paub, dab tsi yuav yog qhov loj ntawm 5 mole ntawm so2?

5 moles ntawm SO2 yuav yog 320,325g. 1 mole ntawm SO2 muaj ib pawg 64,065 g (kwv yees). Qhov no suav nrog kev txheeb ze pawg tooj liab (32.065g / mol ) thiab oxygen (16.00g / mol ).

Yuav ua li cas xam cov grams rau moles?

Hloov ua lwm yam grams rau moles , pib bymultiplying tus naj npawb ntawm atoms los ntawm qhov hnyav atomic rau txhua yam hauv cov compound. Tom qab ntawd, ntxiv tag nrho koj cov lus teb ua ke kom pom cov molar loj ntawm qhov sib xyaw. Thaum kawg, faib tus naj npawb ntawm grams ntawm lub compound los ntawm molar mass ntawm lub compound mus nrhiav tus naj npawb ntawm moles.
