I need to know the solubility of potassium chloride in g / 100 mL of H2O at 60.0 Celsius from both the experimental and official solubility curves; also calculate the percent difference between the two values

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.

im not exactly sure but i think its b!
