A gas container was filled with 2.3 moles of nitrogen gas. If the original volume was 3.4 what would be the new volume if the container ended with 5.7 moles of
nitrogen?

V₂ =  8.43 L

Explanation:

Given data:

Initial number of moles = 2.3 mol

Initial volume = 3.4 L

Final volume = ?

Final number of moles = 5.7 mol

Solution:

According to Avogadro law,

The number of moles of gas is directly proportional to its volume. By increasing the number of moles volume also goes to increase.

Mathematical relationship:

    V₁ / n₁     =    V₂ / n₂

By putting values,

3.4 L / 2.3 mol =  V₂ / 5.7 mol

V₂ =  3.4 L× 5.7 mol / 2.3 mol

V₂ =  19.38 L.mol / 2.3 mol

V₂ =  8.43 L

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.
