Chapter 24: Q24.77P (page 1105)

How many joules are released when $1.5$ mol of $239$ Pu decays, if each nucleus releases $5.243$ MeV?

Short Answer

Expert verified

The joules released are ${7.587脳10}^{11} J$ .

Step by step solution

To find how many joules are released

- ${1.5 mol of}^{239} Pu$ decays

- each nucleus releases $5.243MeV$

First, we need to calculate the number of nuclei in $1.5 molof {}^{239}{Pu}$

$Numberofnuclei = 1.50 mol 脳 \frac{{6.022脳10}^{23} nuclei}{1 mol} = 9.033脳 10^{23} nuclei$

Total energy released in $MeV$ is

$Total energy = {9.033脳10}^{23} 苍耻肠濒别颈脳5.243 \frac{MeV}{nuclei} = {4.736脳10}^{24} MeV$

- ${1MeV = 1.602脳10}^{- 13} J$

Therefore, the number of joules released is

${4.736脳10}^{24} MeV = {4.736脳10}^{24} 惭别痴脳 \frac{{1.602脳10}^{- 13} J}{1MeV} = {7.587脳10}^{11} J$

Hence the joules released are ${7.587脳10}^{11} J$
