Question

3. A solution containing of common salt in 320g of water ,calculate interms of mass

percentage of the solution. ​

Answer 1

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%
