Answer 1

Answer:

Mass of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g

concentration of solution=

$\frac{mass \: of \: solute}{mass \: of \: solution \: } \times 100 \\ = \frac{40}{360} \times 100 \\ = 11.11\%$

Hence, the concentration of the solution is 11.11%
