  1. Answer:

    “23.896%” is the right answer.

    Explanation:

    The given values are:

    Mass of NaCl,

    = 51.56 g

    Mass of H₂O,

    = 165.6 g

    As we know,

    ⇒  Mass of solution = [tex]Mass \ of \ (NaCl+H_2O)[/tex]

                                     = [tex]51.56+164.2[/tex]

                                     = [tex]215.76 \ g[/tex]

    hence,

    ⇒ [tex]Mass \ percent =\frac{Mass \ of \ NaCl}{Mass \ of \ solution}\times 100[/tex]

                               [tex]=\frac{51.56}{215.76}\times 100[/tex]

                               [tex]=23.896 \ percent[/tex]
