The chemical element that has a density of approximately 7.1 g/cm³ is copper (Cu). Copper is a soft, malleable metal with excellent electrical conductivity. Its density can vary slightly depending on the specific form and purity of the material, but it generally falls within the range of 8.9 g/cm³. However, if you are looking for a substance with a density around 7.1 g/cm³, you might be referring to an alloy or a specific compound rather than a pure element.
To clarify, when discussing densities, it’s important to specify the context. While pure copper is denser, some copper alloys or certain mixtures might have a density close to 7.1 g/cm³. Always check the specific material properties when dealing with densities in chemistry and materials science.
