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
11.%
22.2%
10%
20%
Correct answer is C
Mass of Solution = Mass of Solute + Mass of Solvent → 20g + 180g
: Mass of Solution = 200g
Mass Percent = \(\frac{Mass of Solute}{Mass of Solution} * 100%\)
Mass percent = \(\frac{20}{200} * 100%\)
Mass percent = 10%
