So here in this question it is given that, at a particular temperature, the partial pressure, that is, p1 for nitrogen, is 0 .78m, and its concentration, which is denoted as c1, is equal to 5 .3, multiplied with 10 to the power minus 4m.
00:19
And we have to find out the partial pressure for nitrogen, which is denoted as p2, when the concentration, that is c2, is equal to 1 .1, multiplied with 10 to the power minus 3 m.
00:34
Now, here we will use the henry law.
00:40
And according to this law, it is c, that is the concentration.
00:46
This is equal to k .h multiplied with p.
00:52
So here, kh stands for the henry's constant...
