Question

A solution contains 40g of common salt in 320g of water. Calculate the

concentration in terms of mass by mass percentage of the solution. ​

Answer 1

Answer:

11.11 %

Explanation:

solute(common salt) - 40g.

solvent(water)- 320g.

solution- mass of solute+mass of solvent.

40g+320g.

360g.

concentration of solution in terms of mass by mass = mass of solute / mass of solution × 100

= 40/360 × 100

= 11.11%
