How many particles are present in 2 moles of mercury (Hg)?

• A. 1.204 × 10^{24} particles
• B. 2.000 × 10^{24} particles
• C. 3.011 × 10^{23} particles
• D. 6.022 × 10^{23} particles

Answer: (A)

Verified step by step guidance

1. Identify the quantity given: 2 moles of mercury (Hg).
2. Recall that 1 mole of any substance contains Avogadro's number of particles, which is \$6.022 \times 10^{23}$ particles/mole.
3. Set up the calculation to find the total number of particles by multiplying the number of moles by Avogadro's number: \(\text{Number of particles} = 2 \text{ moles} \times 6.022 \times 10^{23} \text{ particles/mole}\).
4. Perform the multiplication of the numerical values and keep track of the powers of ten separately: multiply 2 by 6.022 and multiply the powers of ten accordingly.
5. Express the final answer in scientific notation to represent the total number of particles in 2 moles of mercury.
