[|Home Page] How To Turn Liters Into Grams In order to turn liters of a solution into grams, one must have two givens. The two givens must be the volume of solution and the concentration of the solution. Next, you divide the concentration of the solution by 1 liter of solution. Then you multiply that answer by the volume of the solution. This cancels the liter unit and you are now left in moles of the solute. Finally you convert the moles of solute into grams. To do this you multiply the answer by the molar mass of the solute.

Given: 3 liters of solution ; concentration of solution is .5 moles of NaCl Find: The grams of solute (NaCl) in solution
 * Sample Problem:**
 * 1) (.5 moles of NaCl / 1 liter of solution) x 3 liters of solution= 1.5 mols of NaCl ( The liters cancel out and you are left in moles.)
 * 2) (1.5 mols of NaCl x 58.35 grams of NaCl) / 1 mol of NaCl= **87.5 grams of NaCl** (The mols cancel and you are left in grams)
 * So, a 3 liter solution of .5 M NaCl has 87.5 grams of NaCl in it.
