Answer:
11.11%
Explanation:
total weight of solution=40+320=360
mass by mass percentage of solution
=(mass of solid÷total mass of solution) x 100
=(40 ÷ 360)×100
=11.11%

Answer:11.1%
Explanation:
Mass of solute (salt) = 40g
Mass of solvent (water) = 320g
Mass of the solution = Mass of solute + Mass of solvent
= 40g + 320g
= 360g
Mass percentage of solution
Mass of solute/ Mass of solvent x 100
= 40/360 x 100
11.1%
