    Answer:

    1.47 M

    Explanation:

    First we convert 86.00 g of NaCl into moles of NaCl, using the molar mass of NaCl:

    • 86.00 g ÷ 58.44 g/mol = 1.472 mol NaCl

    Then we convert 1000 mL into liters:

    • 1000 mL / 1000 = 1.0 L

    Finally we can calculate the molarity of the solution:

    • Molarity = moles / liters
    • 1.472 mol / 1.0 L = 1.472 M
