Molality is greater than molarity because the volume increases when the solute dissolves in water so now the volume of the solution is greater than the mass of the water. If there is very little solute (dilute solution) then it is a good assumption that the volume does not change and molarity equals molality.

From the mass of each iron(II) ammonium sulfate and the volume of KMnO4 used calculate the molarity of each KMnO4 solution, as well as the average molarity (You will need the balanced redox reaction to do this). Part 2: Analysis of the Unknown. Prepare 2 samples of the iron unknown just as you prepared the samples of iron(II) ammonium sulfate.

Normality is defined as the number of equivalents of solute per liter of solution and is often used in acid-base chemistry. Understanding equivalents requires knowing something about how a reaction works. For example, sulfuric acid with a formula of H 2 SO 4 donates 2 separate protons. Using the molar mass of sulfuric acid, and knowing that one ...
