WebSo what I did was start with my given molarity as mol/L. I assumed there wouldn't be enough solute to drastically affect density and so I changed 1 L to 1000g, so I now have mol/1000g. Then I multiply by the molar mass of the solute (NaOH - 39.998) so I'm now g NaOH/1000g solution. Then I multiply the whole thing by 1000 to get ppt, right? WebThe molar mass M is a physical property. It is defined as the mass of a given substance divided by its amount, and its SI units are kg mol −1. The term relative molar mass (RMM) is also used. This is defined as “the average mass of the molecule divided by 1/12 of the mass of an atom of the nucleide C 12 .”.

WebAbnormal Molar Masses. The theoretical values of molecular mass, when calculated from the colligative properties of solutions, are sometimes found to differ from the experimentally obtained values.These values are often referred to as abnormal molar masses. Van’t Hoff explained that when solutes are dissolved in a solvent they dissociate into ions.
