WebThe relationship between molarity, moles and volume are shown below. where M = molarity (M or mol/L), n = number of moles (mol) and v = volume (L). Step 1: Determine which formula to use. We were given the number of moles of the substance and the volume of solvent used. We do not know the concentration in molarity. WebAug 27, 2024 · Calculate the pKa with the formula pKa = -log (Ka). For example, pKa = -log (1.82 x 10^-4) = 3.74. What is the formula for Ka? Ka and Kb values measure how well an acid or base dissociates. Higher values of Ka or Kb mean higher strength. General Ka expressions take the form Ka = [H3O+] [A-] / [HA]. Is pKa and Ka the same?
