i just wanaa ask that alpha particles are He2+.we know that He2+ have a mass of 4g. this means alpha

None

i just wanaa ask that alpha particles are He2+.we know that He2+ have a mass of 4g. this means alpha particles should also have 4g mass but mass of alpha particles=mass of protons+mass of neutrons=2

Mass of 1 mole of alpha particle = mass of 2 moles of proton + mass of 2 moles of neutrons = 2+2 = 4 g
