Explanation:

1 mole is defined as the number of particles in 12 g of C12 (Carbon 12). If it were 24 g, instead of 12 g, then the weight of 1 mole of a substance would equal 2 times the atomic or molecular mass in g.

So, in other words, the mole is related to the mass of an element in the following way: 1 mole of C-12 atoms has 6.022x10^23 atoms and a mass of 12 g.

Answer: C. Equal to its atomic mass
