Answer:
estimated mass will be 70 mass of neutron plus mass of proton
Explanation:
we didn't consider electron mass as it's very less ie. in minus 32 kgs and it's under constant circular motion ,it's momentum will be very less .but protons and neutrons stays inside the nuclear and constitute majority of mass of the atom
