Question:

Calculate the weight/volume percent composition, or %(W/V), of 455 ml of solution containing 15.0 g of sucrose.

Solution:

Weight/volume percent is defined as:

$$w/v\% = \frac{\text{mass of the solute } (g)}{\text{volume of solution } (mL)} \cdot 100\%$$ $$w/v\% = \frac{15.0\ g}{455\ mL} \cdot 100\% = 3.3\%$$

Answer: 3.3%
