In alpha and beta decay the parent element and the daughter element will be different isotope and not the same.
This is because as alpha particles comes out; the new element will have two less in atomic number; that is the atomic number will reduce by two and the mass number will reduce by four. While in a beta particle decay, the new element will have one higher in atomic number; that is the atomic number will increase by one.
Answer:

Explanation:
Hello,
In this case, since the molarity is defined as the ratio of the moles of the solute to the volume of the solution in liters:

For the given volume and molarity, we solve for the moles of ammonium sulfate (solute) as shown below:
