Answer:
\(AB_{3}\)
Step-by-step explanation:
Given : \(A_{3}B_{9}\)
To Find : Which represents the empirical formula for\(A_{3}B_{9}\)?
Solution:
Definition of Empirical Formula - A formula that gives the simplest whole-number ratio of atoms in a compound.
\(A_{3}B_{9}\)
To reduce it in simplest form
Divide the subscript numbers by 3
So, the resultant : \(AB_{3}\)
Thus the empirical formula for \(A_{3}B_{9}\) :
\(AB_{3}\)
