* Copper is denser than bronze. This means that a given volume of copper will weigh more than the same volume of bronze.

* Bronze is an alloy of copper and tin. This means that the specific weight of bronze will vary depending on the proportions of copper and tin used.

So, the answer depends on the specific composition of the bronze.

* If the bronze has a high percentage of copper, it will be heavier than pure copper.

* If the bronze has a lower percentage of copper (and a higher percentage of tin), it will be lighter than pure copper.

Let me know if you have a specific bronze composition in mind, and I can give you a more precise answer!
