Answer 2

Mass  of common salt (solute)=40 g

Mass of water (soluted) =320 g

Mass of solution=320+40g

 =360 g

concentration of solution =

$\frac{Mmass \: of \: solute}{mass \: f \: solution} \times 100$

$\frac{40}{360} \times 100$

$= 11.11\%$

Hence, the concentration of the solution is 11.11%
