Strategy:
 Molarity () is a concentration term that defines the number of moles of solute present in exactly one liter of a solution. Calculate the moles of  and divide by the volume in liters.

Step 1: Calculate the molar mass of } \ce{NaCl} 	ext{
- Atomic mass of 
- Atomic mass of 
- Molar mass

Step 2: Determine moles of } \ce{NaCl} 	ext{

Step 3: Calculate Molarity ()
Volume = 500 mL = 0.5 L.
