sommer: examples and translations in context. 1  Par consÃ©quent, si nous voulons vraiment la dÃ©mocratie et l'Ã©galitÃ© devant la loi, nous devons sommer l'armÃ©e turque de se retirer de Chypre, tout comme nous exigeons de l'armÃ©e syrienne qu'elle quitte le Liban.
This number, Avogadro's number, is 6.022x10 23. The mass in grams of one mole of a compound is equal to the molecular weight of the compound in atomic mass units. One mole of a compound contains 6.022x10 23 molecules of the compound.The mass of 1 mole of a compound is called its molar weight or molar mass.The units for molar weight or molar mass are grams per mole. Here is the formula for determining the number of moles of a sample:ne mole of a compound contains 6.022x10 23 molecules of the compound. The mass of 1 mole of a compound is called its molar weight or molar mass. The units for molar weight or molar mass are grams per mole. Here is the formula for determining the number of moles of a sample:
But here's what I do know: One mole is a unit of measurement, a number. One mole is equal to 6.02*10^23 of anything. In this case, you have that many O2 molecules. If you have the molar mass of an atom of oxygen, then that is how many grams one mole of that atom weighs.ating Newest Oldest. Best Answer: O2 is a gas and i think it means there is 2 mole of oxygen and its mass would be 32g/mole given you multiply 2*16. whereas if you were asked about oxygen it would only mean one mole of O and its mass would be 16 g/mole.
