The given data is for h .i.
00:05
Hydrogen iodide which is given as number of moles is 3moles, 3 .00 moles.
00:10
They are given and the temperature is given as 483 kelvin and the volume is given as 3 .5 litres.
00:17
This is the given information.
00:19
So let us do for the wonderful equation, wonderful equation, present wonderful equation p plus a divided a n divided by b whole square multiplied by b minus n b is equal to n r this is a wonderful equation for h i molecule the a value is a 6 .621 atmosphere liter square mole square whereas the b value 0 .0530 litre per mode this is the a and b value for h .i.
01:04
So from this 1t can be calculated as nrt divided by v minus nv minus 8 multiplied by n by whole power 2, which is nothing but number of moles we know that 3.
01:19
3 multiplied by 0 .0821 multiplied by 4883 divided by 3 .50 minus 3 multiplied by 0 .50 minus 3 multiplied by 0 .0530 minus 6 .221 multiplied by 3 divided by 3 .5 whole square.
01:43
If we solve this one, we will get the p value as 33 .993 atmosphere.
01:50
So this is the answer for the first subpart of the question.
01:53
Coming to the second support of the question, in the second support of the question, according according to ideal gas equation, we know that pv is equal to nrt.
02:06
So from that p is equal to nrt by v.
02:09
So number of modes is 3, 0 .0821 multiplied by 483 divided by 3 .5.
02:19
If we saw this one, we will get 33 .948 atmosphere...
