Answer:

Explanation:

100 persent transmission implies that the T=1

Therefore using the previous result we have

$1+\frac{\sin^2\sqrt{\frac{2m}{\hbar^2}(E+V_0)}a}{4\frac{E}{V_0}\frac{(E+V_0)}{V_0}}=1
$

$\sin\sqrt{\frac{2m}{\hbar^2}(E+V_0)}a=0\Rightarrow \sqrt{\frac{2m}{\hbar^2}(E+V_0)}=0\Rightarrow E=-V_0
$

The depth of the well for 100% transmission should be

$V_0=-0.7~{\rm{eV}}$

First of all, we need to convert the energy produced from kilojoules to calories. 1 kJ corresponds to 239.1 cal, therefore:

$E=18.9 kJ \cdot 239.1 =4519.4 cal$

And so now we can calculate the energy value of the oil:

$E_v = \frac{E}{m}=\frac{4519.4 cal}{0.50 g}=9038.8 cal/g$
