Jul 01, 2004 · A 1 molar solution is a solution in which 1 mole of a compound is dissolved in a total volume of 1 litre. For example: The molecular weight of sodium chloride (NaCl) is 58.44, so one gram molecular weight (= 1 mole) is 58.44g. Now that you have the molar mass of the solute, you need to multiply the number of grams of solute in the solution by a conversion factor of 1 mole over the formula weight (molar mass) of the solute. This will give you the number of moles of the solute for this equation.Units of Concentration The molar mass of a compound can be calculated by adding the molar mass of the individual elements. 22.99 + 35.45 = 58.44 g/mol Making Solutions You just calculated the molar mass of sodium chloride to be 58.44 g/mol. To determine how to make a stock solution of sodium chloride, use the formula: g = M x L x molar mass Molarity is defined as the moles of a solute per liters of a solution. pH is a figure expressing the acidity or alkalinity of a solution on a logarithmic scale on which 7 is neutral, lower values are more acid and higher values more alkaline.
