Well, depending on who you ask I should add. Using solute mass over
solvent volume is not exactly my understanding of how it works. In the
case of water is your solvent, which is almost always, it makes no
difference. In the case of other solvents, my understanding has been
that the percentage refers to the mass of a volume of pure solvent. In
this case one liter of mercury would be somewhere around 13,570 grams.
In which case a 6% w/v solution would be 814g of solute with whatever
solvent was required to bring the volume of the entire solution to one
