ANSWER

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g

concentration of solution=

×100=11.11%

Hence, the concentration of the solution is 11.11%..

Answer 2

Answer:

Concentration = Mass of Solute / Volume of Solution

= 40 / 200

= 1 / 5 g/ml

= 0.2 g/ml
