SpletMolar concentration is the amount of a solute present in one unit of a solution. Its units are mol/L, mol/dm 3, or mol/m 3. Molar concentration, also known as molarity, and can be denoted by the unit M, molar. To prepare 1 L of 0.5 M sodium chloride solution, then, as per the formula, use 29.22 g of sodium chloride (0.5 mol/L * 1L * 58.44 g/mol ... SpletOne molecule has a mass of 1.0079 + 1.0079 = 2.0158 u, while 1 mol H2has a mass of 2.0158 g. A molecule of H2O has a mass of about 18.01 u; 1 mol H2O has a mass of 18.01 g. A single unit of NaCl has a mass of 58.45 u; NaCl has a molar mass of 58.45 g.
