Answer 1

"23.896%" is the right answer.

Step-by-step explanation:

The given values are:

Mass of NaCl,

= 51.56 g

Mass of H₂O,

= 165.6 g

As we know,

⇒ Mass of solution =
`Mass \ of \ (NaCl+H_2O)`

=
`51.56+164.2`

=
`215.76 \ g`

hence,

⇒
`Mass \ percent =(Mass \ of \ NaCl)/(Mass \ of \ solution)* 100`

`=(51.56)/(215.76)* 100`

`=23.896 \ percent`
