No of atom in 44gm of co2

44gms of CO2 contains 6.023 *10^23 molecules.

But 1 molecules contains a total of 3 atoms .

So 44gms of CO2 contains 18.069*10^23 atoms.

it is to be noted that an alpha particle is an helium nucleus. so it contains 2 protons 2 neutrons and has a mass number of 4. when alpha decay particles are ejected from the nucleus it gets transformed into an atom which has atomic number less than 2 and a mass number less than 4.

an equation that could represent alpha decay is radium 226 decay of alpha particle forms radon 222.
