Answer
$NaBrO$
Work Step by Step
In order to solve this problem, first recall the chemical formula of bromite, which is $BrO-$. Sodium, on the other hand, is an alkali metal, so it has a charge of +1. Since hypobromite has a charge of 1-, there is one hypobromite ion for every one sodium ion. Therefore, the chemical formula is $NaBrO$.
