is its momentum in MeV/c?

This is off topic for this group, but the formula is,

p=(mu)*mass*(speed)


All you do is plug in your values.

Indeed it is off topic, but while we are responding, then it is
worth mentioning that at 0.8c, relativistic effects must be considered.
I believe this is what the original poster was asking about.
