PPT-Making Molar Solutions

From Solids What are molar solutions A molar solution is one that expresses concentration in moles per volume Usually the units are in molL molL can be abbreviated as M or Molar solutions are prepared using. com From Liquids. (More accurately, from stock solutions). Making molar solutions from liquids. Not all compounds are in a solid form. Acids are purchased as liquids (“stock solutions”).
