A chemist wishes to determine the density of an unknown purple liquid. She constructs a cylindrical aluminum container, whose inside radius measures 0.375 inches, with a height of 3.500 inches. When empty, this cylinder has a mass of 89.749 g. When filled with purple liquid its mass was 296.200 g. What is the density of this liquid, in terms of g/cm3?

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.

if it's not useful, feel free to report for mistake in answer.
