What is the Q value in units of MeV in each of the following processes?

i) The spontaneous fission of^{232}U^{92}to^{145}La^{57}and^{87}Br^{35}

ii) The neutron induced fission of^{232}U^{92}to^{146}La^{57}and^{87}Br^{35}

Explain why heavy nuclei such as^{232}U^{92}do not usually undergo fission.

[Masses given in atomic mass units are^{232}U^{92}232.0372;^{145}La^{57}144.9217;^{146}La^{57}145.9255;^{87}Br^{35}86.9203; n 1.0087]

Attempt

There are loads of equations for different Q values depending on the type of decay it undergoes. I'm not sure which to use.

Also, I think I need to convert the atomic mass units into something else but I'm not entirely sure what?

I basically don't know where to start with it!
