The molar mass of XCl₃ • 6H₂O is 266.44 g/mol. How many grams of Cl atoms (the molar mass of Cl is 35.45 g/mol) are in a 1.20 g sample of XCl₃ • 6H₂O?

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.
