A.3 moles H2
1 mole N2
I think it is correct
By adding together the number of protons and neutrons and multiplying by 1 amu, you can calculate the mass of the atom.
The nuclear reaction occurring is known as alpha-decay, and during this process, an alpha particle is released from a heavy radioactive nucleus to form a lighter more stable nucleus. The alpha particle is equivalent to a helium nucleus, which means it contains 2 protons and two neutrons (net charge of +2)
The decay equation is:
Rn → Po + α
