**Question:** How many atoms of carbon are contained in 47.6 g of Al₂(CO₃)₃? The molar mass of Al₂(CO₃)₃ is 233.99 g/mol. **Multiple Choice Answers:** - ☐ \(2.87 \times 10^{25}\) C atoms - ☐ \(1.23 \times 10^{23}\) C atoms - ☐ \(3.68 \times 10^{23}\) C atoms - ☐ \(2.96 \times 10^{24}\) C atoms **Explanation:** To solve this problem, you need to calculate the number of moles of Al₂(CO₃)₃ in 47.6 g, and then determine the number of carbon atoms in that amount. Each mole of Al₂(CO₃)₃ contains 3 moles of CO₃, and thus 3 moles of carbon atoms. Use Avogadro's number (\(6.022 \times 10^{23}\) atoms/mol) to find the total number of carbon atoms.
