Question 1 (1 point) (05.01 LC)
Which of the following best defines the molar mass of a substance? (1 point)
O a
Mass, in grams, of each particle of the substance
Ob
Total mass, in grams, of 100 particles of the substance
Ос
Mass, in grams, of the nucleus of the substance's atoms
d
Total mass, in grams, of all the particles in one mole of the substance

its not a choice. you dont choose if you want to be gay or straight.

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.
