Question

A solution contains 40 g of common salt on 320 g of water calculate the concentration in terms of mass by mass percentage of the solution​

Answer 1

Answer:

see

Step-by-step explanation:

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%

Answer 2

Step-by-step explanation:

The concentration of the solution is

11.11%.
