Answer:

A. 4.

Explanation:

  • We can use the relation:

<em>no. of moles (n) = mass/molar mass.</em>

mass = 64.0 g, molar mass = 16.0 g/mol.

∴ no. of moles (n) = mass/molar mass = (64.0 g)/(16.0 g/mol) = 4 mol.

Each substance has a unique set of properties that depends on the kinds of atoms it has and how the atoms are connected, or bond

Both diamond and graphite are allotropes of carbon. Diamond has a high tensile strength but graphite does not.

<h3>What is a molecular model?</h3>

A molecular model is used to describe the actual behavior of a chemical compound based on the kind of bonds that exists in the molecule. Now we are talking about diamond and graphite.

Graphite is composed of hexagonal rings of carbon atoms that form layers that are held together by weak Van Der Walls forces hence they can slide over each other. This is the reason why graphite does not have a high tensile strength.

On the other hand, diamond is made up of octagonal rings of carbon atoms which are rigid and form a strong covalent network solid that explains why graphite has a high tensile strength.
