Graphite Composition Explained: Carbon Content

This section explains the composition of pure graphite, focusing on its carbon content. Graphite is a common form of elemental carbon. It's an allotrope of carbon, meaning it's one of the different crystalline forms that pure carbon can take. Understanding the composition of materials like graphite is fundamental in chemistry and material science.

Analyzing Pure Graphite's Carbon Percentage

The question asks what percentage of pure graphite is carbon. Let's look at the options provided:

• 0% of carbon
• 2% of carbon
• 6.67% of carbon
• 100% of carbon

Understanding Graphite Purity

Graphite is, by definition, a form of carbon. When we refer to pure graphite, we are talking about a sample that consists exclusively of carbon atoms arranged in a specific crystalline structure (layers of graphene). While natural graphite samples might contain trace impurities, the theoretical and ideal composition of pure graphite is 100% carbon.

Therefore, the percentage of carbon in pure graphite is the maximum possible.

Conclusion on Graphite Composition

Based on the definition of pure graphite as an elemental form of carbon, its composition is entirely carbon.

• Pure graphite consists solely of carbon atoms.
• The carbon content in pure graphite is 100%.
