Question

A solution contains 40 g of common salt in 320 g of water. Calculate the concentration in terms of

mass by mass percentage of the solution.​

Answer 1

Explanation:

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g

×100=11.11%

Hence, the concentration of the solution is 11.11%

Answer 2

Answer:

amount of solute is equals to 40 gram of common salt

amount of solvent is equals to 300 gram of water

amount of solution is equals to solvent plus solute is equals to 360 gram

concentration = solute / solution

=40/360

=1/9
