A common organic solvent used in the laboratory vaporizes readily. If the pressure of the compound's vapor in a flask is 193 mmHg at 25 °C, and the density of the vapor is 0.426 g/L, what is the molar mass of the compound?

fe 55.85 g/mol and h2o 18.02 g/mol.

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.
