Gram molecular mass yog qhov loj hauv grams ntawm ib lub mole ntawm cov tshuaj molecular. Gram molecular mass yog tib yam li molar mass. Qhov txawv tsuas yog tias gram molecular loj qhia cov chav tsev loj los siv. Gram molecular mass yuav raug qhia hauv grams lossis grams ib mole (g/mol).
1g ntawm mole yog dab tsi?
In the SI system, the mole has about 6.022 140 × 10 23 particles. Qhov no txhais tau hais tias yog gram mole, txawm hais tias SI units tau lees paub tias qhov no yog mole. Xwb, ib (kilogram mole) yog sib npaug rau gram moles, thiab yog li ntawd yuav xav tias muaj sij hawm 6.022 140 × 10 23 particles.
Puas molar mass per gram?
Molar mass txhais tau tias qhov hnyav hauv grams ntawm ib lub mole ntawm ib yam khoom. Cov units ntawm molar mass yog grams ib mole, abbreviated li g/mol.
