I agree with typhoonn Master as well as The Transformer but i would also like to add, it is relative to 1/12 of a carbon atom.(I believe at least)

Eh, no. You're getting Avogadro's number mixed up with the definition of the atomic mass unit (amu). Avogadro's number is a measure of quantity, not mass.

ELEMENTS AND COMPOUNDS QUIZ

Thank you Channel28. Alright this is not really my quiz but as Channel28 mentioned above, it's basically a revival. Unlike my other 2 quizzes, I have no intention of rewarding GPs for this one. This is just for fun for you science and chemistry lovers.And, I'm not a Chemistry expert but I will also ensure I give tough questions now and then.The rules are more or less the same. I won't go in to great detail:

• Just stick to the forum rules.
• I will decide on the number of points for each question.
• Have fun

ALRIGHT LET'S BEGIN!Question 1. 1 pointName the gas we breathe which is used in respiration.
