How many molecules are present in 0.16 moles of carbon dioxide (CO_2)?

• A. 2.6 × 10^{23} molecules
• B. 9.6 × 10^{22} molecules
• C. 4.8 × 10^{22} molecules
• D. 1.0 × 10^{24} molecules

Answer: (B)

Verified step by step guidance

1. Identify the given quantity: 0.16 moles of carbon dioxide (CO\_2).
2. Recall that 1 mole of any substance contains Avogadro's number of molecules, which is approximately \$6.022 \times 10^{23}$ molecules/mole.
3. Set up the calculation to find the number of molecules by multiplying the number of moles by Avogadro's number: \(\text{Number of molecules} = 0.16 \text{ moles} \times 6.022 \times 10^{23} \text{ molecules/mole}\).
4. Perform the multiplication of the numerical values and combine the powers of ten accordingly (do not calculate the final value here, just set up the expression).
5. Express the final answer in scientific notation to match the format of the given options.
