Correct Answer: Option C
Explanation

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%

There is an explanation video available below.
