Vedclass · Answer

(C) The mass of the solution is the sum of the mass of the solute and the mass of the solvent. Mass of solution $= 20 \, g + 200 \, g = 220 \, g$. The formula for $\% \, w/w$ is: $\% \, w/w = \frac{	ext{mass of solute}}{	ext{mass of solution}} 	imes 100$. Substituting the values: $\% \, w/w = \frac{20 \, g}{220 \, g} 	imes 100 = \frac{2000}{220} \approx 9.091 \%$. Thus,the correct option is $C$.

Calculate the $\% \, w/w$ of a solution formed by dissolving $20 \, g$ of solute in $200 \, g$ of water.
