If you have 2 moles of Li, how many atoms of lithium do you have?

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

Answer: (C)

Verified step by step guidance

1. Understand that the problem asks for the number of atoms in 2 moles of lithium (Li).
2. Recall Avogadro's number, which is the number of atoms in one mole of any substance: \$6.022 \times 10^{23}$ atoms/mole.
3. Set up the calculation by multiplying the number of moles by Avogadro's number: \(\text{Number of atoms} = \text{moles} \times 6.022 \times 10^{23}\) atoms/mole.
4. Substitute the given value of moles (2 moles) into the equation: \(\text{Number of atoms} = 2 \times 6.022 \times 10^{23}\) atoms.
5. Perform the multiplication to find the total number of atoms (do not calculate the final number here, just set up the expression).
