Vedclass · Answer

(D) The percentage strength of a solution can be expressed in different ways depending on the physical states of the solute and solvent: $1$. Mass percentage $(w/w)$: $\frac{	ext{Weight of solute}}{	ext{Weight of solution}} 	imes 100$ $2$. Mass by volume percentage $(w/v)$: $\frac{	ext{Weight of solute}}{	ext{Volume of solution}} 	imes 100$ $3$. Volume percentage $(v/v)$: $\frac{	ext{Volume of solute}}{	ext{Volume of solution}} 	imes 100$ Since all these formulas represent valid ways to express the percentage concentration of a solution,the correct answer is $D$.

Which of the following represents the percentage strength of a solution?
