Tocalculate ? considering 100% ionic bond 
 
 = 4.8 × 10–10 × 1.2 × 10–8esu cm (1A = 10-8 cm)
 

              = 5.76× 10–18 esu cm = 5.76 D

 The percent ionic character = Observed dipole moment/Calculated dipole moment assuming 100% ionic bond × 100

              ? % ionic character = 1.92/5.76 × 100 =  33.33
