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 option: c
Mass of solution = Mass of solute + Mass of solvent → 20g + 180g
Hence, Mass of solution = 200g
Mass Percent = \(\frac{Mass of Solute}{Mass of Solution} * 100%\)
Mass percent = \(\frac{20}{200} * 100%\)
Mass percent = 10%
