If 50.0 mL of 0.150 M magnesium bromide is combined with 200 mL of 0.110 M sodium bromide what is the molarity of the bromide ion in the resulting solution? (assume volumes are additive)

mols MgBr2 = M x L
mols Br = twice that.

mols NaBr = M x L
mols Br = mols NaBr.

M Br = (total mols Br/total volume in L)
