Answer:

the concentration of the solution is 11.11%

Explanation:

Mas  of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

              =360 g

Hence, the concentration of the solution is 11.11%

Answer:

11.11%

Explanation:

40+320=360

40/360×100=11.11%

mass concentration percentage is11.11%
