Ib pawg hauv grams tus lej sib npaug rau lawv qhov hnyav muaj ib lub mole ntawm molecules , uas paub tias yog 6.02 x 10^23 (Avogadro tus lej). Yog li koj muaj x grams ntawm asubstance, thiab qhov hnyav molecular yog y, ces tus naj npawb ntawm moles n = x / y thiab tus naj npawb ntawm molecules = nmultiplied byAvogadro tus lej.

Ib yam li ntawd, koj pom cov grams hauv molecules li cas?

Thaum koj paub qhov hnyav molecular ntawm ib qho compound, koj paub ntau npaum li cas Avogadro tus naj npawb ntawm cov compound hnyav. grams . Rau nrhiav tus lej ntawm molecules inasample, faib qhov hnyav ntawm tus qauv los ntawm qhov hnyav ntawm onemoleto tau tus naj npawb ntawm moles, ces muab faib los ntawmAvogadro tus lej.

Ib yam li ntawd, gram molecule yog dab tsi? Noun. gram ntawm molecule (plural cov grammolecule ) (chemistry) Tus nqi ntawm ib qho compound uas nws loj nyob rau hauv grams nws ntawm nws molecular hnyav; a mole.

Cov lus nug tseem yog, koj ua li cas xam cov molecules?
