What is the concentration of a solution containing 37.9 mL of bromine diluted to 250 mL with water?

Question

I don't know if the M₁V₁ = M₂V₂ equation would work.

Answer 1

Actually, for this kind of question, you would normally use M1V1 = M2V2 except you don't know M1or M2. So, this question cannot be answered as written.
