Molar Concentration Formula
The concentration of this solution is one molar (1.00 mol/L or 1.00M) Example 2: What is the concentration of a solution made by dissolving 175.5g of NaCl in enough water to make 2.00 liters of solution? Answer: 175.5g NaCl 1 mol = 3.00 mol of salt dissolved in 2.00 liters so 3.00mol = …
