dipole moment is defined as product of charge and distance between between.
[tex]P = qd[/tex]
[tex]q = 1.6 \times 10^{-19} C[/tex]
[tex]d = 80 pm = 80 \times 10^{-12} m[/tex]
[tex]P = (1.6 \times 10^{-19})(80 \times 10^{-12})[/tex]
[tex]P = 1.28 \times 10^{-29} Cm[/tex]
so above is the dipole moment of the given charges
