Calculating Molarity of a NaCl Solution

In a laboratory setting, a chemist prepares a solution by dissolving 10 grams of sodium chloride (NaCl) in enough water to make a total volume of 500 mL. The chemist notes that the solubility of NaCl at room temperature is approximately 357 grams per liter (g/L). Following this, the chemist performs a series of dilutions and reactions with the prepared NaCl solution.

The chemist is interested in determining the molarity of the resulting NaCl solution. Molarity (M) is defined as the number of moles of solute per liter of solution. Given that the molar mass of NaCl is approximately 58.44 g/mol, what is the molarity of the initial NaCl solution?
