dipole moments

How do you determine dipole moments in a molecule, is it based off oxidation number?

[Ariel Peng 3J]

Dipole moments in a molecule are determined by the distribution of electron density, which is influenced by the electronegativity of the atoms and the molecular geometry. It's not directly based on oxidation numbers.
Electronegativity Difference: The greater the difference in electronegativity between bonded atoms, the more polar the bond, leading to a larger bond dipole moment.
Molecular Geometry: The spatial arrangement of the atoms affects how bond dipoles sum up. In symmetric molecules, dipole moments may cancel out, while in asymmetric molecules, they can add up to create a net dipole moment.

Dipole moments are based on the polarity of a molecule. Look at the Lewis structure and see is it non polar or polar, if its polar, then it will have a dipole moment. If its non polar like SF6 even though it contains polar bonds, then it will not have a net overall dipole moment as they will cancel.
