**Thu Oct 04, 2018 8:56 pm**Sodium bromide, NaBr, which is used to produce AgBr for use in photographic film, can itself be prepared as follows.

Fe + Br2 -> FeBr2

FeBr2 + Br2 -> Fe3Br8

Fe3Br8 + Na2CO3 -> NaBr + CO2 + Fe3O4

What mass of iron, in kilograms, is needed to produce 2.50 t of NaBr? Note that these equations must first be balanced!

After balancing the equation, do I have to convert 2.50t to grams in order to continue? If so, what is the conversion rate?
