Mass is the amount of matter in an object. Mass is often measured in kilograms or grams. The masses of two objects are compared using a balance. Weight is the downward pull on an object due to gravity. Weight is often measured in newtons or pounds, using a spring scale.

In alpha and beta decay the parent element and the daughter element can be
Angelina_Jolie [31]
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.

How many moles are in 325mL of 1.25M (NH4)2SO4
mote1985 [20]

Answer:

n_{solute}=0.406mol(NH_4)_2SO_4

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:

M=\frac{n_{solute}}{V_{solution}}

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

n_{solute}=M*V_{solution}=1.25\frac{mol}{L}*325mL*\frac{1L}{1000mL}  \\\\n_{solute}=0.406mol(NH_4)_2SO_4

Best regards.
