Molarity is a concentration term that relates moles of solute and total volume. We use the symbol M for Molarity and it means moles/L. If I put 1.000 mole of a solute like NaOH(s) into a 1.000 L volumetric flask and add water until the total volume is 1.000L, I have created a 1.000M solution. Anytime I use that solution, I can calculate the moles of NaOH in any volume of that solution. An example is if I have 0.320...
