    The molarity of the solution is 2.736 M

    calculation

    Step 1: find moles of table salt (Nacl)

    moles = mass : molar mass

    from periodic table the molar mass of table salt (NaCl) = 23+35.5 = 58.5 g/mol

    moles is therefore = 40 g: 58.5 g/mol = 0.684 moles

    Step 2: find molarity

    molarity = moles: volume in liters

    = 0.684 moles: 0.25 L=2.736 M
