D
12.01 g
Verified step by step guidance1
Understand that the mass of one mole of atoms of an element is called the molar mass, which is numerically equal to the atomic mass of the element expressed in grams per mole.
Identify the atomic mass of carbon from the periodic table, which is approximately 12.01 atomic mass units (amu).
Recognize that 1 mole of carbon atoms contains Avogadro's number of atoms, which is \$6.022 \times 10^{23}$ atoms.
Use the relationship that the molar mass in grams per mole is equal to the atomic mass in amu, so the mass of one mole of carbon atoms is 12.01 grams.
Therefore, the correct mass corresponding to one mole of carbon atoms is 12.01 g.
