Weak acids do not … WebLet's start with the weak acid. We're gonna use the molarity equation. Molarity is equal to moles over liters. So for our weak acid, the concentration is 2.0 molar, so we plug that in, and the volume is 100 milliliters which is equal to 0.100 liters. Solving for x, we find that there are 0.20 moles of acetic acid.
