Asample of propane, c3h8, contains 10.6 moles of carbon atoms. how many total moles of atoms does the sample contain?

38.86 mole atoms

Explanation:

Given data:

moles of carbon in C₃H₈ = 10.6 mol

total moles atoms = ?

Formula:

number of moles of carbon × total moles of atoms / number of carbon atoms

Solution:

10.6 × 11/ 3 = 38.86 mole atoms

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.
