    Explanation:first, let us calculate the number of mole of NaCl present in the solution. This is illustrated below:

    Molarity = 0.5M

    Volume = 100cm^3 = 100/1000 = 0.1L

    Mole = ?

    Molarity = mole / Volume

    Mole = Molarity x Volume

    Mole of NaCl = 0.5 x 0.1 = 0.05mole

    Now we can obtain the mass of NaCl as follows:

    Molar Mass of NaCl = 23 + 35.5 = 58.5g/mol

    Mole of NaCl = 0.05mol

    Mass of NaCl = ?

    Mass = number of mole x molar Mass

    Mass of NaCl = 0.05 x 58.5

    Mass of NaCl = 2.93g
