A diatomic molecule has a dipole moment of 1.2D if the bond length is 1.0 x 10^-8 cm, what fraction of charge does exist on each atom?

Dear Student, 
Please find below the solution to the asked query: 

Dipole moment is calculated by the following formula:

μ = q ×× lwhere μ is dipole moment = 1.2 D = 1.2 × 3.336 × 10-30 Cmq is magnitude of chargel is distance between charges or bond length = 1× 10-8 cm or 1 × 10-10 m

q =1.2 × 3.336 ×10-301×10-10q = 4×10-20 Cfraction of charge = 4 ×10-201.6 × 10-19= 0.25

Hope this information will clear your doubts about determining the fraction of charge on a diatomic atom with a dipole moment.
