If the concentration of chloride ion (Cl-) is later found to be 0.020 molar (M), how much sodium chloride (NaCl) salt was added to the beaker? the Gram Molecular Weight (GMW) of Na= 23 g/mol, and the GMW of Cl is ...
WebIt is defined to be 1/12 of the mass of one atom of carbon-12 and in older works is also abbreviated as "amu". Also, important in this field is Avogadro's number (N A) or Avogadro's constant (6.0221 x 10 23). The term "mole" is defined in that one mole of a substance with a molecular (or atomic) mass of one (1), will have a mass of 1 gram. Or 1 ... WebThus, since the atomic mass of iron is 55.847 amu, one mole of iron atoms would weigh 55.847 grams. The same concept can be extended to ionic compounds and molecules. One formula unit of sodium chloride (NaCl) would weigh 58.44 amu (22.98977 amu for Na + 35.453 amu for Cl), so a mole of sodium chloride would weigh 58.44 grams.
