The mass of the nucleus is 2.34348 * 10^(-26) kilogram. The mass of a neutron is always greater than a proton as basically speaking a neutron is composed of a proton and electron and other subatomic particles.

What part of an atom carries most of its mass?

The vast majority of an atom's mass is within the nucleus; the electrons orbiting the nucleus, which do contain the same amount of charge as the nucleus(albeit negative), have virtually no mass when compared to the nucleus. In fact many scientific disciplines disregard the mass of electrons altogether.
