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

• A. 3.01 × 10^{23} atoms
• B. 6.022 × 10^{23} atoms
• C. 1.00 × 10^{23} atoms
• D. 12.04 × 10^{23} atoms

Answer: (B)

Verified step by step guidance

1. Understand that 1 mole of any substance contains Avogadro's number of particles (atoms, molecules, ions, etc.). Avogadro's number is approximately \$6.022 \times 10^{23}$ particles per mole.
2. Since the problem asks for the number of atoms in 1.00 mole of magnesium (Mg), and magnesium is an element composed of individual atoms, the number of atoms is directly related to the number of moles by Avogadro's number.
3. Write the relationship: Number of atoms = (number of moles) \(\times\) (Avogadro's number). In this case, Number of atoms = \$1.00 \text{ mole} \times 6.022 \times 10^{23} \text{ atoms/mole}$.
4. Perform the multiplication to find the total number of atoms in 1.00 mole of magnesium. This will give you the exact number of atoms present.
5. Compare your calculated value with the given options to identify the correct answer.
