Is the mass of deuteron twice the mass of proton and that of alpha particle 4times the proton???

Dear student,
As we know that Protons and neutrons have approximately the same mass, about 1.67 x 10-24 grams.
Deutron is a nucleus of one Proton & one Neutron and no electron so its mass will be approximately double the mass of proton.
Similarly, Alpha particles consist of two protons and two neutrons bound together into a particle identical to a helium-4 nucleus, its mass is four times the mass of proton.
