These types of animals are referred to as D. scavengers.
Scavenger animals are adapted to feed on dead and decaying meat and usually feed on the carcasses left over by predatory animals. An example is how vultures pick off the meat from a zebra carcass that has been left over after a lion pack has finished eating from it.
N (moles) = m (mass in grams) / M (molar mass)
the molar mass of magnesium is 24.31
so n = 0.422 / 24.31
which = 0.0174 mol
