If you are given the number of molecules in an unidentified chemical compound can you calculate the number of moles in this sample

By using mole concept

Explanation:

We are given:

An unknown compound having some number of molecules.

To calculate the number of moles that are contained in a sample, we use mole concept:

According to mole concept:

1 mole of any compound contains number of molecules.

Using this relation and applying unitary method, we can easily calculate the number of moles of a compound.

For Example: A sample of water contains number of molecules.

So, by using mole concept:

number of molecules are contained in 1 mole of a compound.

So, number of molecules will be contained in of water

b..

is the correct one

explanation:

covalent bonds form as valence electrons are shared between two atoms. lewis structures and structural formulas are common ways of showing the covalent bonding in organic molecules. formal charge describes the changes in the number of valence electrons as an atom becomes bonded into a molecule.
