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:
The idea here is that you need to use neon's molar mass, which tells you what the mass of one mole of the element is, to determine how many moles you have in that 5.9-g sample. Once you know how many moles you have, you can use Avogadro's number to find the number of atoms. So, neon has a molar mass of 20.18 g/mol, which means that every mole of neon has a mass of 20.18 g. Now, you know that one mole of any element contains exactly 6.022â1023 atoms of that element - this is Avogadro's number.
