Problem

The average density of Earth is

5.52\times10^{3}\,\text{kg\,m}^{-3}

, whereas that of a neutron star is about

3.5\times10^{17}\,\text{kg\,m}^{-3}

. By how many orders of magnitude is the neutron star denser than Earth (use the usual rounding rule for order of magnitude)? a) 15 b) 14 c) 13 d) 12
