**Answer:**

4. Which of these properties is considered during recrystallization process?

- *Temperature*

- Mass

- Volume

- Density

5. A cube of copper was found to have a mass of 630 g. What are the dimensions of the cube given the density of copper to be 8.94 g/cm³.

- 70.47 cm

- 8.39 cm

- 4.13 cm

- 8.26 cm

$$\rho = \frac{m}{V}$$ $$V = \frac{m}{\rho} = a^{3}$$ $$a = \sqrt[3]{\frac{m}{\rho}} = \sqrt[3]{\frac{630\ g}{8.94\ g/cm^3}} = 4.13\ cm$$

6. Why is ethanol not a suitable solvent for extracting aqueous solutions?

- Due to its high boiling point

- *Due to its solubility in water*

- Due to its flammability

- All of the above
