Purest Carbon?

Hello first of all brilliant.org and friends let me clear about the purest form of carbon ,in nature three forms of pure carbon graphite ,coal,and diamond are present.but all they have some impurities when found in nature.Amorphous carbon is actually made up of tiny crystal like bits of graphite with varying amounts of other elements which are considered as impurities.e.g the coal industry divides the coal into various grades depending upon the amount of carbon in the coal and the amount of impurities.the highest grade anthracite contains 90% carbon .so in my point of view my answer anthracite is correct as maximum percentage of carbon content in it as compared to other

This discussion board is a place to discuss our Daily Challenges and the math and science related to those challenges. Explanations are more than just a solution — they should explain the steps and thinking strategies that you used to obtain the solution. Comments should further the discussion of math and science.

When posting on Brilliant:

Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

That's always the issue between "theoretical" and "empirical". For example, when a chemistry question says "water is added to a NaCl solution", we do not say "ah, but water is impure and contains other ions, so there could be other reactions .... "

Theoretically, graphite and diamond (amongst others) are considered to be in pure form (without any impurities). Empirically, impurities will exist. If you wanted to talk about empirical diamond, it would have been clearer to talk about the grade of the diamond.
