Answer:
Mass of solute - NaCl =40gm
Mass of solvent - water =320gm
Mass of solution =(40+320) gm
=360gm
Concentration in terms of Mass by mass percentage =mass of solute /mass of solution *100
=40/360*100%=11.11%
Hope this help. Mark as brainliest if it's good

Answer:
Mass of solute (salt) = 40g
Mass of solvent (water) =320g
we know ,
Mass of solution = Mass of solute + Mass of solvent
= 40g + 320g
= 360g
Mass percentage of solution
= Mass of solute / Mass of solution × 100
= 40 / 360 × 100
= 11.1 %
HOPE THIS HELPS YOU
Have a nice Day.....
