xam Molar Mass

Molar loj yog cov pawg ntawm cov khoom muab faib los ntawm tus nqi ntawm cov khoom ntawd, ntsuas hauv g / mol. Piv txwv li, atomic pawg titanium yog 47.88 amu lossis 47.88 g / mol. ua 47,88 grams ntawm titanium, muaj ib tug mole, los yog 6.022 x 10²³ titanium atoms

Raws li, koj yuav nrhiav tau cov mis molecular los ntawm molar loj li cas?

Empirical qauv hnyav = (1 x 12.01g/mol) + (2 x 1.01g/mol) + (1 x 16.00g/mol) = 30.02g/mol. Faib cov molar loj rau cov molecular formula los ntawm empirical formula loj . Qhov tshwm sim yog txiav txim siab pes tsawg zaus los muab cov ntawv sau rau hauv qhov empirical qauv kom tau molecular formula.

Ib yam li ntawd, puas molar loj hauv grams? Molar Mass . Cov hnyav hauv grams ntawm ib mole ntawm cov khoom hu ua molar loj . Piv txwv li, carbon molar loj yog 12.011 g / mol, thiab magnesium molar loj yog 24.3050 g /mol.

Ib yam li ntawd, nws yog nug, koj yuav hloov molar loj li cas?

xam Molar Mass Molar loj yog cov pawg ntawm cov khoom muab faib los ntawm tus nqi ntawm cov khoom ntawd, ntsuas hauv g / mol. Piv txwv li, atomic pawg titanium yog 47.88 amu lossis 47.88 g / mol. Nyob rau hauv 47.88 grams titanium, muaj ib tug mole, los yog 6.022 x 10²³ titanium atoms.

Yuav ua li cas koj pom cov molar loj ntawm ib tug tsis paub?

Sample teeb meem: Molar Mass los ntawm Freezing Point Depression Kauj Ruam 1: Sau cov khoom paub thiab npaj qhov teeb meem. rau xam lub molality ntawm cov tshuaj. Tom qab ntawd siv molality equation rau xam cov moles ntawm solute. Tom qab ntawd faib cov grams ntawm solute los ntawm moles los txiav txim qhov molar loj.
