Question

Quizplus · Accepted Answer

The average mass of a carbon atom (12.011) is a weighted average of the masses of all carbon isotopes based on their natural abundance. No single carbon atom actually has a mass of 12.011; they are either slightly lighter or heavier, such as carbon-12 or carbon-13. Therefore, the chance of picking an atom with the exact average mass is 0%.
