Question

How many moles of atoms are present in 7.36 × 10²⁴ free oxygen atoms?

• A. 11.4 moles
• B. 10.2 moles
• C. 13.4 moles
• D. 12.2 moles

Answer 1

The correct option is D 12.2 moles

We know that,
1 mole atoms = $6.023\times {10}^{23}$ atoms
No. of. moles of atoms in 7.36 × 10²⁴ free oxygen atoms = $\frac{7.36\times {10}^{24}}{6.023\times {10}^{23}}$
= 12.2 moles of atoms
