Molar of Molarity
A molar solution consists of one gram molecular weight of a compound dissolved in enough water to make one liter of solution.
A gram molecular weight is the molecular weight of a compound in grams. For example, the molecular weight of sulfuric acid (H2SO4) is 98. A one M solution of sulfuric acid would consist of 98 grams of H2SO4 dissolved in enough distilled water to make one liter of solution.
