SOLVED: If the same mass of Na2SO4 (MW: 142 g/mol) and K2SO4 (MW: 174 g/mol) were weighed and used for the gravimetry experiment, which will yield a greater amount of precipitate? Assume that the experiment was done correctly.K2SO4 because it has a larger molecular weight.They will yield the same amount of precipitate because the same mass was initially weighed.Indeterminate; it will depend on the amount of BaCl2 used.Na2SO4 because it has a smaller molecular weight.
