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:
To find the number of molecules in a gas sample, given the pressure, volume, and temperature of the sample: 1  Figure out how many moles of CO 2 gas you have.2  Use Avogadro's number to convert moles into molecules: 0.0211915 mol Ã 6.02Ã1023 molecules/mol = 1.28 Ã 1022 molecules. Convert molecules of gas to moles of gas, using the mole-to-molecule conversion. 2  Assuming the gas sample is ideal, you can easily compute the volume of the gas using the ideal gas equation of state because you know the temperature, pressure, and moles of gas.
