convert to moles
14.7g Na = 0.639 moles Na
7.9g Br = 0.099 moles Br
Since each mole of Na reacts with 1 mole of Br, you should be able to figure out the result. (There will be some Na left over.)
Anna, you can't get lazy in chemistry and not use caps when needed. na is not anything but two letters and I have no idea what og br is. Starting a sentence with a capital letter at least tells us where the sentence starts. A period helps us know where the sentence ends.
This is not a tweet or facebook board and if you want help it behooves you to post the question with as much clarity as possible. Steve probably is smarter than I; he may have figures out that og is a typo and you intended to write of.
