how would one determine the molarity of NaOH using the balanced equation HCl NaOH= NaCl H2O

Titrate with an acid of known concentration.
Then use Macid X Vacid = Mbase X Vbase

What's a certain indicator that a molecule is polar?

Jonnie: I am not sure I understand your question. Are you asking how you can tell if a molecule is polar or not? Look at the electronegativities of the bonded atoms and at the shape of the molecule and try to figure out if the centers of + charge and - charge overlap or not. If they overlap, the molecule is nonpolar. If they are separated, it is polar.
