Question

A solution contains 20 g of common salt in 240 g of water. Calculate the

concentration in terms of mass by mass percentage of the solution.​

Answer 1

Answer:

Answer

Mas  of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

               =360 g

concentration of solution=massofsolutionMmassofsolute×100

36040×100=11.11%

Hence, the concentration of the solution is 11.11

Hope's it helps you

Answer 2

Answer:

7.69%

Explanation:

mass of solute=20 gm

mass of solvent=240

mass of solution=260

mass%= mass of solute×100/mass of solution

= 20×100/260=7.69%
