      J) Molar Concentration (p. 96) Concentration: how much of a substance is in a given amount of solution. Symbol = [ ], E.g. [NaCl] means “concentration of NaCl” Concentrated = high concentration. Dilute = low concentration. Molar Concentration: how many moles of a substance in 1 L of solution. Symbol = M. E.g. 3M means “3 mol/L”

      The molar concentration of a solution of glucose, for example, is the same as its formality. For substances that ionize in solution, such as NaCl, molarity and formality are different. For example, dissolving 0.1 mol of NaCl in I L of water gives a solution containing 0.1 mol of Na+ and 0.1 mol of Cl .

      Molarity is a means of representing a solution’s concentration. In other words, it expresses how much dissolved solute can be expected from a given volume of solution. The . molar concentration or molarity, M, of a solution is used to indicate the number of moles of solute per liter of solution:

    • Molar concentration - Wikipedia

      When you are calculating the concentration of a solution, you must do so by calculating the number of moles of solute dissolved into the total volume of solution. Example 1: Molar mass of salt (NaCl) is 58.5 g/mol, so if you dissolve 58.5g of salt in enough water to make 1.00 liter of solution, you have one mole of solute dissolved per liter of ...
