The dipole moment of $KCl$ is $3.336 \times 10^{-29}$ coulomb meter which indicates that it is a highly polar molecule. The inter atomic distance between $K^+$ and $Cl^{-}$ in this molecule is $2.6 \times 10^{-10}\;m$ Calculate the dipole moment of $KCl$ molecular if there were opposite charges of one fundamental unit located at each nucleus. Calculate percentage ionic character of $KCl$
