Areaction produces 0.415 mol of h2o. how many molecules of water are produced?

1 mol of anything has 6.02x10^23 particles (Avagadros constant)

so do 0.415 x the constant =2.4983x10^23

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.
