In this question, the motive is to calculate the volume of h2s .s .o.
00:05
4.
00:06
So let us write the balanced equation first, and it will be h2s .o.
00:11
It is in aqua state.
00:12
Now it will be plus k -oh, that is potassium hydroxide.
00:18
It is also in aqua state, and it is giving us h2o, which is in liquid state.
00:25
So here it will be l, and then it is plus k2s0.
00:30
Which is the salt of potassium, right? so it is also in the aqua state.
00:36
And here it will be two.
00:38
So this is a balanced equation.
00:40
Now as we can see that one mole of h2so4, so here it will be h2 -s -o -4, that is sulfuric acid, reacts with two moles of, here it will be k -o -h, that is potassium hydroxide.
00:56
Now let us calculate the moles of k -o -h.
01:00
In our problem.
01:01
And the moles of k -o -h will be, let's write, moles of, and then it is k -o -h...
