Dipole moment

If you have a polar molecule (i.e. HCl) and you're trying to find the dipole moment using the formula u=qd, where u is the dipole moment, q is the charge and r is the distance etween the two partial charges, what value do you use for q? Do you use the charge on H or the charge on Cl?

Think about this for a minute and you will answer your own question. 😉

the mag of the charge is the same on each atom, but does the sign of the charge matter? is the dipole moment always a positive number?

Charges are the same on both?

Charges are the same on both?

I think that's the definition. U should have 2 equal and opp charges. I'm not sure if that applies to HCl.
