A0.250g sample of hydrocarbon undergoes complete combustion to produce 0.845g of co2 and 0.173g of h2o. what is the empirical formula of this compound?

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.
