Also, dilute acetic acid does not conduct electricty as well as dilute nitric acid at the same concentration. Does this mean that acetic acid is a strong acid or a weak acid?
I hope someone can help me because my teacher did not explain it very well. Please help.

glacial acetic acid is pure and doesn't disassociate, thus there are no ions, thus you can't conduct electricty.
dilute acetic acid is in solution with water, where it does, to a small extent disassociate and form ions, thus you can conduct electricity
acetic acid is a weak acid b/c it doesn't disassociate fully, this so there are fewer ions in solution in comparison to an acid that does disassociate fully, like nitric which is a strong acid, thus acetic acid is less able to conduct electricity than an equal concentration of nitric acid

Glacial acetic acid is nearly pure, so there is no water in it. Without water, the acetic acid isn't dissociated into hydronium ions and acetate ions. And the ions in solution are what will conduct electricity.
Even in water, acetic acid is a weak acid -- it does not dissociate 100% the way the hydrochloric or nitirc acid would. So even at the same concentration, it does not produce as many ions. Thus it will not condict electricity as well.
Hope that helps.

Acetic acid produces free H3O+ and OH- ions when dissolved in water. These ions allow current to flow through the water. Since acetic acid is a weak acid, it does not form a particularly large concentration of ions, so the water does not become a particularly good conductor of electricity.

Glacial acetic acid does not dissociate so there are noions to conduct the e-. In water it does dissociate some and does conduct some. Acetic acid is a weak acid . Vinegar is 5% acetic acid.

Glacial acetic acid is 100% acetic acid. It is called glacial because it is frozen, melted, refrozen to its freezing point of about 15degC to free it from impurities, then remelted. 100% Acetic acid behaves nothing like water. In particular, glacial acetic acid is almost entirely covalently bonded, nonionized HC2H3O2. However, if you put some acetic acid into water, it ionizes somewhat into H+ and C2H3O2- ions and conducts electricity somewhat. Acetic acid is a weak acid. HNO3 is always completely ionized into H+ and NO3-, and so is a strong acid, strong electrolyte.
