Well ,This is a hypothetical question .Generally Atomic mass of Helium is 4 amu.
I hope this question was Based on The Formula ,Atomic mass=Number of neutrons+Number of protons.
Given ,Atomic mass of Helium =40
Number of protons=2
Hence ,Number of neutrons=40-2=38
Number of Neutrons in the helium atom of mass 40 possessing 2 protons is 38 neutrons .
