A solution contains 20g of solute in 180g of solvent. If the solvent is water, what is the concentration of the solution in terms of mass by mass percentage

A.

11.%

B.

22.2%

C.

10%

D.

20%

Correct answer is C

Mass of Solution = Mass of Solute + Mass of Solvent → 20g + 180g

: Mass of Solution = 200g

Mass Percent = MassofSoluteMassofSolution100

Mass percent = 20200100

Mass percent = 10%
