For example, when a question asks about two equivalents of bromine, does that mean Br2 OR 2Br2?

Thanks

1. Strictly speaking, I think that means 2Br2 but I need the equation to tell for sure. Often that refers to Br. For example, if we are talking about the equation of
Cl2 + 2Br- ==> 2Cl^- + Br2 we SHOULD say two equivalents of bromide ion but I often hear two equivalents bromine. The latter is not right.
