Final answer:
The molarity of sodium chloride in the solution is 1.0 M.
Step-by-step explanation:
Molarity (M) is a unit used to measure the concentration of a solution. It is calculated by dividing the number of moles of solute by the volume of the solution in liters. In this case, we have 0.50 moles of sodium chloride (NaCl) and a volume of 500 mL, which is equivalent to 0.500 L.
To find the molarity, we divide the moles of NaCl by the volume:
Molarity (M) = Moles of NaCl / Volume of Solution
Molarity (M) = 0.50 mol / 0.500 L
Molarity(M) = 1.0 M
