To convert weight/weight percentage to weight/volume percentage:
\[ W/V \% = \frac{W/W \% \cdot \text{Density of Solvent}}{100} \]
Where:
Weight/weight percentage (W/W %) is a measure of the concentration of a solution expressed as the mass of solute divided by the mass of the solution, multiplied by 100. Weight/volume percentage (W/V %) is a measure of the concentration of a solution expressed as the mass of solute divided by the volume of the solution, multiplied by 100.
Let's assume the following values:
Using the formula:
\[ W/V \% = \frac{10 \cdot 1.2}{100} = 0.12 \]
The weight/volume percentage is 0.12%.
