calculate the density and # of moles of a 10% Bromine Solution used in an experiment. Does the 10% refer to v/v or g/v in solution? I used 350 ul of the Bromine Solution. Im guessing that would mean there are 35 ul of pure Br2 in the 350 ul, but I am not sure. The density of pure bromine is 3.1 g/mL, is that what I should use in the calculations? The 10% solution part is really what is tripping me up here.
