Answer:
6 Neutrons
Step-by-step explanation:
The number of Protons/Electrons (Protons and electrons are proportional to each other), added with the number of the neutrons that the atom has always equals the mass of the atom.
This claim can be represented with this formula
Protons/Electrons + Neutrons = Atomic Mass
Electrons = 6
Atomic Mass = 12
6(Electrons) + Neutrons = 12(Atomic Mass)
Neutrons = 12 - 6
Neutrons = 6
Therefore, the amount of Neutrons in a carbon molecule are 6
