Final answer:
To determine the concentration of a sodium chloride solution with 0.17 moles of NaCl dissolved in 750.0 mL, convert the volume to liters and use the molarity formula C = n / V. The resulting concentration is 0.227 M.
Step-by-step explanation:
The concentration of a solution is measured as the amount of solute present in a given volume of solvent. When dissolving 0.17 moles of sodium chloride (NaCl) in a solution, we can use the definition of molarity to find the concentration. Molarity is defined as moles of solute per liter of solution (mol/L).
To calculate the concentration of the NaCl solution:
-
Therefore, the concentration of the solution is 0.227 M sodium chloride.
