Ethanol has a density of 1.3 g/mL. What would be the mass of 146.4 mL?

The answer is

Explanation:

The mass of a substance when given the density and volume can be found by using the formula

From the question

volume of ethanol = 146.4 mL

Density = 1.3 g/mL

The mass is

mass = 1.3 × 146.4

We have the final answer as

Hope this helps you

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.
