Guida verificata passo dopo passo1
Understand that the atomic weight of an element (given as 12 for carbon) represents the mass of one mole of its atoms in grams.
Recall that one mole of any element contains Avogadro's number of atoms, which is approximately \(6.022 \times 10^{23}\) atoms.
Since the atomic weight is 12, this means one mole of carbon atoms weighs 12 grams.
Therefore, the weight of one mole of carbon atoms is directly equal to the atomic weight expressed in grams.
Conclude that the correct answer is 12 grams, as it corresponds to the molar mass of carbon.
