10% bromine solution
« on: June 22, 2006, 12:44:44 AM »
I used a 10% bromine solution for a reaction that added bromine to an alkene. I added 350 ul of the solution, and in developing a stoichiometry table I find myself with a problem. Since it is a 10% bromine solution does this mean that it is (ml Br2 / ml solution) X 100% ? Specifically, a volume - volume percentage? If this is true then

350 ul * (1 ml / 10^3 ul) * (1 ml Br2 / 10 ml solution) = .035 ml Br2 ? However, without the density how can I obtain the amount in mmol?

Most likely it is 10% w/w solution and - if no other information is given - you should assume its density is that of solvent or consult density tables.

I am assuiming it is not a water solution, as these are not as concentrated. If its water solution, you may probably assume 1 g/mL.
