The size of a hydrogen atom is about \( 0.5 \text{ \AA} \). The total atomic volume of 1 mole of hydrogen atoms in \( \text{m}^3 \) is closest to: (Take \( \pi = 3.14 \), Avogadro's number \( N_A = 6.02 \times 10^{23}\text{ mol}^{-1} \))

1. A
   \( 3.15 \times 10^{-7}\text{ m}^3 \)
2. B
   \( 5.24 \times 10^{-31}\text{ m}^3 \)
3. C
   \( 6.02 \times 10^{-23}\text{ m}^3 \)
4. D
   \( 1.31 \times 10^{-31}\text{ m}^3 \)
