Dipole moment - calculation of percentage ionic character


Question: The dipole moment of HBr is 2.60×1030 and the interatomic spacing is 1.41. What is the percentage ionic character of HBr?


What I know is that the percentage ionic character is observed dipole moment divided by calculated dipole moment × 100.


The calculated dipole moment is charge on electron×radius of molecule.


However, how would I convert interatomic spacing into radius?
