You prepare a solution by dissolving a known mass of solute (often a solid) into a specific amount of a solvent. One of the most common ways to express the concentration of the solution is M or molarity, which is moles of solute per liter of solution.
Prepare 1 liter of 1.00 M NaCl solution.
First calculate the molar mass of NaCl which is the mass of a mole of Na plus the mass of a mole of Cl or 22.99 + 35.45 = 58.44 g/mol
- Weigh out 58.44 g NaCl.
- Place the NaCl in a 1 liter volumetric flask.
- Add a small volume of distilled, deionized water to dissolve the salt.
- Fill the flask to the 1 L line.
