Problem

A sample contains

1.6\times10^{5}

nuclei at

t=0

. A plot of

N

versus

t

shows that only

4.0\times10^{4}

nuclei remain after

18\,\text{h}

. Using only this information, how many nuclei will remain after

27\,\text{h}

? a)

1.0\times10^{4}

2.0\times10^{4}

2.7\times10^{4}

3.2\times10^{4}
