How many molecules of BrF2 form when 384g Br2 react with excess F2?

equation: Br2 + 5F2 ---> 2BrF5

I really just need the guidelines to figure out the problem, i can figure out the rest from there. Please and thank you.

    You must mean BrF5.
    Convert 384 g Br2 to moles.
    Using the coefficients in the balanced equation convert moles Br2 to moles BrF5. Then 1 mol contains 6.02 x 10^23 molecules.

    That's what I meant, thank you for you help DrBob222
