David Sang and Graham Jones Solutions for Chapter: Nuclear Physics, Exercise 4: Questions

(a) The mass of an atom of ${}_{26}{}^{56}\mathrm{Fe}$ is $55.934937\mathrm{u}$. Calculate its mass in $\mathrm{kg}$.

(b) The mass of an atom of ${}_8{}^{16}\mathrm{O}$ is $2.656015\times {10}^{-26} \mathrm{kg}$. Calculate its mass in $\mathrm{u}$.

Table gives the masses (in u) of several particles. $\left(\text{Avogadro constant} N_{\mathrm{A}}=6.02\times {10}^{23}{ \mathrm{mol}}^{-1}\right)$. Use the table to determine to three significant figures:

(a) the mass in $\mathrm{kg}$ of a helium- 4 nucleus.

Table gives the masses (in u) of several particles. $\left(\text{Avogadro constant} N_{\mathrm{A}}=6.02\times {10}^{23}{ \mathrm{mol}}^{-1}\right)$. Use the table to determine to three significant figures:

(b) the mass in gram (g) of $1.0$ mole of uranium-235 nuclei.
