The resource that the scientist is most likely working with is ores. Copper is typically extracted from its ore using different methods that highly depend on the nature and composition of the ore. Examples of copper ores are sulphide, silicate, carbonate, and sulphate ores. Copper extracted from these ores still undergo further processing and purification.

Density equals Mass/Volume. The equation for this problem would be 1.62 kg/205 mL. If it’s easier, this can be converted to 1620 g/205 mL. The answer would be 7.902 (rounded to the nearest thousandth). Good luck!
I think that pressure will affect the solubility of gasses the most. The reason why I think this is that gasses are affected the most by pressure change. By definition solids and liquids are not easily affected by pressure by how close the molecules are to each other in both of those phases.
I hope this helps. Please let me know if you have any further questions or need any clarification.
