For polystyrene ratio, so we can say that for polystyrene ratio, the r -square -g upon the molecular weight raised to 1 by 2 is going to be equal to 0 .275a.
00:21
And this is mold per gram raised 1 by 2.
00:27
Now what will happen, the rg which is represented by radiation, gyration radius.
00:33
This is our gyration radios.
00:38
Now what can happen in this case, the rg value, if we square this, so this will become what? this is going to become rg square.
00:47
If we square all the terms, so rg square, so it is going to be 0 .275 a mole per gram, half, and we have to whole square this part multiplied by the molecular weight times half.
01:07
So this will be the term.
01:09
Then we can say the rg value is going to be equal to the square of everything.
01:14
So this is 0 .275 a mole per gram raised to half multiplied by 1 .10 raised to 5 gram per mole raised to half.
01:30
And when we do this, this comes out to be giving the value of rg is equal to 0 .275.
01:36
This mole per gram half and this gram per mole will get cancelled...
