For example, the atomic weight of the element chlorine is 35.453, determined by averaging the atomic masses and relative abundances of its two main naturally occurring isotopes, which have atomic masses of about 35 and 37.
Which of the following has the greatest mass, in grams? 1 atom of gold (Au) 0.5 mol lead (Pb) atoms 2.0 mole of chlorine (Cl) atoms 25 atoms of mercury (Hg) .5 mol lead. first, eliminate the atoms. none of them can compare to quantities in moles. now you need to find the molecular weight of lead and chlorine. molecular weight of lead is about 207 g/mol, so half a mole of lead is 103.5 g. molecular weight of chlorine is about 35.5 g/mol, so two moles of chlorine is about 71 grams.
