How many magnesium atoms are present in 1.00 mole of Mg?

• A. 6.022 × 10^{22} atoms
• B. 6.022 × 10^{23} atoms
• C. 3.01 × 10^{23} atoms
• D. 1.00 × 10^{3} atoms

Answer: (B)

Verified step by step guidance

1. Understand that 1 mole of any substance contains Avogadro's number of particles (atoms, molecules, etc.). Avogadro's number is approximately \$6.022 \times 10^{23}$ particles per mole.
2. Identify that the problem asks for the number of magnesium atoms in 1.00 mole of Mg, so the particles we are counting are atoms of magnesium.
3. Use the relationship: Number of atoms = (number of moles) \(\times\) (Avogadro's number).
4. Substitute the given values into the formula: Number of atoms = \$1.00 \text{ mole} \times 6.022 \times 10^{23} \text{ atoms/mole}$.
5. Interpret the result as the total number of magnesium atoms in 1.00 mole of Mg, which corresponds to Avogadro's number.
