What is the empirical formula of a substance that contains 8.33×10−2 mol of carbon, 0.167 mol of hydrogen, and 8.32×10−2 mol of oxygen?

The empirical formula for the given compound is

Explanation:

We are given:

Moles of carbon =

Moles of hydrogen = 0.167 moles

Moles of oxygen =

To formulate the empirical formula, we need to follow some steps:

For the mole ratio, we divide each value of the moles by the smallest number of moles calculated which is moles.

For Carbon =

For Hydrogen =

For Oxygen =

The ratio of C : H : O = 1 : 2 : 1

Hence, the empirical formula for the given compound is

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.
