Thus, 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. Note that the units grams sodium "cancel out" in the first factor and you are left in units of moles. Moles cancel out in the second factor and the final units are atoms sodium. 3.3h MAS - gram/atom conversions Problem1 How many K atoms are there in a 84.8 gram sample of K? 1.31E+24 atoms Feedback: This is a two-step calculation.
