Explain $\% \, w/V$ and $\% \, w/w$ in brief.

(N/A) Mass by volume percentage $(\% \, w/V)$: It is defined as the mass of the solute in grams dissolved in $100 \, mL$ of the solution.
Mass percentage $(\% \, w/w)$: It is defined as the mass of the component in grams per $100 \, g$ of the solution.
Formula: $\text{Mass } \% \text{ of a component} = \frac{\text{Mass of the component in the solution}}{\text{Total mass of the solution}} \times 100$.
Example for $(\% \, w/w)$: If a solution is $10 \% \, w/w$ glucose in water,it means $10 \, g$ of glucose is dissolved in $90 \, g$ of water,making a total of $100 \, g$ of solution.
