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.
