Guida verificata passo dopo passo1
Understand that 1 mole of any substance contains Avogadro's number of entities (atoms, molecules, etc.).
Recall Avogadro's number, which is approximately \(6.022 \times 10^{23}\) entities per mole.
Since the problem asks for the number of atoms in 1 mole of carbon, recognize that 1 mole of carbon atoms contains exactly Avogadro's number of atoms.
Write the relationship: Number of atoms = (1 mole) \(\times\) (Avogadro's number) = \(1 \times 6.022 \times 10^{23}\) atoms.
Conclude that the number of atoms in 1 mole of carbon is \(6.022 \times 10^{23}\) atoms.
