How many xenon atoms are present in 2.36 moles of xenon (Xe)?

• A. 7.12 × 10^{24} atoms
• B. 1.42 × 10^{24} atoms
• C. 3.93 × 10^{23} atoms
• D. 6.02 × 10^{23} atoms

Answer: (B)

Verified step by step guidance

1. Identify the given quantity: 2.36 moles of xenon (Xe).
2. Recall that 1 mole of any substance contains Avogadro's number of atoms, which is \$6.02 \times 10^{23}$ atoms/mole.
3. Set up the calculation to find the number of atoms by multiplying the number of moles by Avogadro's number: \(\text{Number of atoms} = 2.36 \text{ moles} \times 6.02 \times 10^{23} \text{ atoms/mole}\).
4. Perform the multiplication of the numerical values and handle the powers of ten accordingly to get the total number of atoms.
5. Express the final answer in scientific notation to clearly represent the number of xenon atoms present.
