0.25 moles of Ca(NO3)2 were used to create a 1.3 M solution. What is the
volume of the solution? (YOUR ANSWER WILL BE IN L SO CONVERT:
1000 ML = 1 L).

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.
