Question

33. A solution contains 40g of common salt in 320 1 mass by mass percentage of the solution ?​

Answer 1

Answer:

This might help you

Explanation:

Mass of solute = 40g

Mass of solution = 40g+320g = 360g

Concentration of solution = Mass of solute /Mass of Solution×100

= 40/360 ×100

= 11.1g

Answer 2

Explanation:mass of solution =320+40=360g

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

=40x100/360=11.11%
