Naval brass, an alloy of copper with zinc and tin, resists corrosion by salt water. A 6.0 kg ship’s bell made of this alloy contains 234g of zinc and 60g of tin. Determine the percent (m/m) of each metal in the bell.

metals are good conductor of electricity. it has free electrons on their surface. according to electron pool theory, each atom present in a metal crystal losses all of its valence electron and as a result a pool of free is form. these pool of electrons are free to move and   conduct electricity easily   while making metal as good conductor.

the correct answer is a. the ability of electrons to flow throughout the metal.
