If HI were 100% ionic, then the charge would be Q=1.60×10−19 C. Using the equation μ=Q×r calculate μ, the expected dipole of HI. Be sure to convert the bond distance, r=161 pm, to meters.
well, p refer to pico based on prefix in Physics pico=10 power of (-12) (ten power of negative 12) 161 has to be converted to this form 1.61 1.61×10>(−10)
