Hello, in this video, we will be solving the question that we see on the screen, where we're given the rest mass of a proton and the rest mass of a neutron.
00:08
And then we're given the total mass of a helium -4 nucleus, which is 4 .002 -602u.
00:16
And we simply need to find out the mass defect of the nucleus in terms of you, obviously.
00:21
Right.
00:22
So first of all, before we work out the mass defect, let's first of all find out what a helium -4 nucleus is made up of.
00:28
A helium -4 nucleus is made.
00:30
Made up of two protons and two neutrons.
00:35
So now that we're given the rest mass of a proton, which is this, and the rest mass of a neutron, which is this, we will be using these values and then subtracting the final helium -4 nucleus weight mass from our addition, from our thumb, to find out the mass effect.
00:57
So if we simply will be doing is we will take two times the mass of one proton, we will then add two times the mass of one neutron and then we will subtract that from the mass of a helium -4 nucleus...
