WebDec 2, 2024 · While molarity is a valuable unit, it does have one main disadvantage. It does not remain constant when temperature changes because temperature affects the volume of a solution. Since you don't physically measure solute in moles, usually you convert grams of solute to moles and then divide this number by liters of solution. WebSep 3, 2024 · Multiply the concentration (0.5 mols/Liters) by the volume of solution you want (0.5 Liters) to find the moles of NaCl you need. 2. Multiply the moles of NaCl by its molar mass (58.44 g/mol) to find the grams of solute needed.
