An unknown compound has the formula AzT. The molar mass of element "A" is 39.22 g/mol. The molar mass of element "T" is 12.78 g/mol. Calculate the molecular weight of AzT. Round to two decimal places.

-be a crystalline solid

- be soluble in water

-conduct electricity

hope this : )

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.
