Problem

A nucleus is found to have a radius of

5.0\,\text{fm}

. Using

R_0 = 1.2\,\text{fm}

and

1\,\text{u} = 1.66\times10^{-27}\,\text{kg}

, which pair of estimates for its mass number

A

and nuclear mass

m

is the most reasonable? a)

A \approx 125,\; m \approx 2.1\times10^{-25}\,\text{kg}

b)

A \approx 46,\; m \approx 7.6\times10^{-26}\,\text{kg}

c)

A \approx 72,\; m \approx 1.2\times10^{-25}\,\text{kg}

d)

A \approx 216,\; m \approx 3.6\times10^{-25}\,\text{kg}
