    Answer:

    2.0 M

    Explanation:

    Step 1: Given data

    • Mass of NaCl (solute): 2.93 g
    • Volume of the solution: 0.025 L

    Step 2: Calculate the moles corresponding to 2.93 g of NaCl

    The molar mass of NaCl is 58.44 g/mol.

    2.93 g × 1 mol/58.44 g = 0.0501 mol

    Step 3: Calculate the molarity of the solution

    Molarity is equal to the moles of solute divided by the liters of solution.

    M = 0.0501 mol/0.025 L = 2.0 M
