Answer
$Q = 8.13~MeV$
Work Step by Step
We can find $Q$:
$Q = (M_i-M_f)~c^2$
$Q = [(1.007825 u+18.998405 u)-(4.002603 u+15.994915 u)]~c^2$
$Q = (0.008712~u)~c^2$
$Q = (0.008712)~(1.66\times 10^{-27}~kg)~(3.0\times 10^8~m/s)^2$
$Q = 1.3015728\times 10^{-12}~J$
$Q = (1.3015728\times 10^{-12}~J)(\frac{1~eV}{1.6\times 10^{-19}~J})$
$Q = 8.13~MeV$
