Let me explain you the question here.
00:02
1 .6m .g.
00:05
Of radioactive rubidium, radioactive rubidium 83.
00:13
So this particular radioactive rubidium, it decays to, it case to krypton 883.
00:21
So how it is decaying to electron capture? two electron capture.
00:28
So here, if half -life of rubidium 83.
00:32
So here rubidium 83 half life it is given as three months.
00:39
So here rubidium 83 will be one year how much? so first of all i want to tell you what is meant by half life.
00:52
Half life.
00:53
So the half life of a reaction it is nothing but time required.
00:59
Time required half life.
01:02
So life it is nothing but time required for a reactant for a reactant.
01:08
To reach to reach one half its initial concentration one half its initial concentration so that is nothing but half life that means that means so here 1 .6mg so it should be here 1 .6m.
01:34
Of rubidium a radioactive rubidium the concentration should become half the concentration should become half.
01:45
So, it becomes half, how much time it takes.
01:50
It is nothing but half life.
01:52
Half refers to the concentration becomes off, which time.
01:58
It takes how much time.
02:00
So coming to the solution here.
02:03
So here, one year means how many months? 12 months...
