The diagram illustrates how the atoms are arranged in a specific crystal. There is one atom at each corner of a cube. Each atom has a mass of $3.5 \times 10^{-25}\,\text{kg}$. The density of the crystal is $9.2 \times 10^{3}\,\text{kg m}^{-3}$. Determine the smallest distance between the centres of two adjacent atoms?
- A$3.8 \times 10^{-29}\,\text{m}$
- B$6.2 \times 10^{-15}\,\text{m}$
- C$3.4 \times 10^{-10}\,\text{m}$
- D$3.0 \times 10^{-9}\,\text{m}$
