How many moles is 24 grams of carbon?

N=24/12
n=2

where n= no. of moles

One mole of a substance is the relative formula mass of the substance in grams. So one mole of carbon has a mass of 12 grams ( because the atomic mass of carbon is 12, from the periodic table). If 12 g of carbon is one mole, how many moles would 24 grams be? 

The  grandmother cell  is a hypothetical  neuronthat represents a complex but specific concept or object.[1]  it activates when a person "sees, hears, or otherwise sensibly discriminates"[2]  a specific entity, such as his or her grandmother. the term was in use at least as early as 1966 amongst staff and students in the department of experimental psychology, university of cambridge, england. a similar concept, that of the  gnostic neuron, was proposed two years later
