In the mole concept, how many copper atoms are present in $1 \mathrm{mol}$ of copper (Cu)?

• A. $6.022\times {10}^{22}$ atoms
• B. $6.022\times {10}^{23}$ atoms
• C. $1.000\times {10}^{24}$ atoms
• D. $63.55$ atoms

Answer: (B)

Verified step by step guidance

1. Recall that one mole of any substance contains Avogadro's number of particles (atoms, molecules, ions, etc.).
2. Avogadro's number is defined as \$6.022 \times 10^{23}$ particles per mole.
3. Since the problem asks for the number of copper atoms in 1 mole of copper, you simply multiply the number of moles by Avogadro's number.
4. Set up the calculation as: Number of atoms = (1 mol) \(\times\) \((6.022 \times 10^{23} \text{ atoms/mol})\).
5. This calculation gives the total number of copper atoms in 1 mole of copper.
