The dipole moment of HBr is `2.60 xx 10^(-30)` C.m and the inteatomic spacing is 1.41`A^0`. What is the percentage ionic character of HBr ?

Explanation

To find the percentage ionic character of HBr, we will follow these steps:

### Step 1: Understand the given data
We have the following information:
- Observed dipole moment (μ observed) of HBr = \( 2.60 \times 10^{-30} \) C.m
- Interatomic spacing (d) = 1.41 Å

### Step 2: Convert interatomic spacing from Ångströms to meters
