    Answer: The molarity of solution will be 0.049 M

    Explanation:

    Molarity is defined as the amount of solute expressed in the number of moles present per liter of solution. The units of molarity are mol/L. The formula used to calculate molarity:

    \text{Molarity of solution}=\frac{\text{Given mass of solute}}{\text{Molar mass of solute}\times \text{Volume of solution (L)}}

    We are given:

    Given mass of sodium chloride = 10 g

    Molar mass of sodium chloride = 58.44 g/mol

    Volume of solution = 3.50 L

    Putting values in above equation:

    \text{Molarity of NaCl}=\frac{10 g}{58.44g/mol\times 3.50}\\\\\text{Molarity of NaCl}=0.049M

    Hence, the molarity of solution will be 0.049 M
