How do you find the mass of a solution

Explanation:

If

Note that this is a measurement SOLELY of

density

. This is likely an aqueous solution, but you have not specified this.

You have not quoted units of concentration, i.e.

Moles of solute

Volume of solution

, and thus we are in the dark.

Explanation:

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.
