Calculate the number of atoms in 52 moles of argon.

Calculate the number of atoms in 52 moles of argon.

Options

  1. A218.8×1023218.8 \times 10^{23}
  2. B545.1×1023545.1 \times 10^{23}
  3. C313.1×1023313.1 \times 10^{23}
  4. D136.3×1023136.3 \times 10^{23}

Correct answer

C. 313.1×1023313.1 \times 10^{23}

Step-by-step solution

Number of atoms = Number of moles \times Avogadro's number

Number of atoms = 52×6.022×102352 \times 6.022 \times 10^{23}

Number of atoms = 313.144×1023313.144 \times 10^{23}

Number of atoms ≈313.1×1023\approx 313.1 \times 10^{23}

Answer: 313.1×1023313.1 \times 10^{23}
