How many moles of carbon atoms are present in 1 mole of carbon dioxide (CO_2)?

• A. 1 mole
• B. 2 moles
• C. 0.5 mole
• D. 3 moles

Answer: (A)

Verified step by step guidance

1. Identify the chemical formula of carbon dioxide, which is \(\mathrm{CO_2}\). This means each molecule contains 1 carbon atom and 2 oxygen atoms.
2. Understand that 1 mole of any compound contains Avogadro's number (\$6.022 \times 10^{23}$) of molecules.
3. Since each molecule of \(\mathrm{CO_2}\) contains exactly 1 carbon atom, 1 mole of \(\mathrm{CO_2}\) molecules contains 1 mole of carbon atoms.
4. Therefore, the number of moles of carbon atoms in 1 mole of \(\mathrm{CO_2}\) is equal to the number of moles of \(\mathrm{CO_2}\) itself, which is 1 mole.
5. Conclude that the answer is 1 mole of carbon atoms per 1 mole of carbon dioxide.
