WebWe did a set of labs where we had to identify what a specific solution was and the molarity of the solution. I identified the solution as KI, but then when it comes to finding the molarity, I have no idea how. I reacted the KI with Pb(NO3)2 and then AgNO3 in test tubes and put the solutions through filters to get the precipitate only. WebMolality is a solution property and is defined as the number of solvent moles per kilogram. Molality’s SI unit is mol/kg. A solution with a 3 molar/kg molality is often defined as “3 molal” or “3 m.”. However, it is …
