Question 11

A nanocrystal of copper has a cubical structure containing approximately 1.25 × 105 atoms. The average spacing between adjacent copper atoms in the lattice is 2.6 × 10-10 m.

Which measurement is the most reasonable estimate for the width of this cubical nanocrystal?

A

3.3×10−5 m3.3 \times 10^{-5}\text{ m}3.3×10−5 m

B

9.2×10−8 m9.2 \times 10^{-8}\text{ m}9.2×10−8 m

C

1.3×10−8 m1.3 \times 10^{-8}\text{ m}1.3×10−8 m

D

1.3×10−9 m1.3 \times 10^{-9}\text{ m}1.3×10−9 m
