Hello, in this question here we need to find out the partial pressure of the dry gas, dry hydrogen gas.
00:08
So from the table we get that is the vapor pressure of the water at vapor pressure of water at 21 degrees celsius.
00:23
The temperature of the chemical reaction rate is 21 degrees celsius and atmospheric pressure of wet gas in this experiment in this, of this atmospheric pressure.
00:34
It is 750 .1 mhm hg which is measured from barometer and here this vapor pressure here it is 18 .7 mhm hg it is there so by dalton's law of partial pressure dalton states that that is because that is the total pressure it is of a mixture of a gas it is equals to the subter.
01:09
Of the pressure that each would exert if were present.
01:14
So therefore that will be equal to p total, it is equal to p1 plus p2 plus p3 plus and so on till pn.
01:23
Here these are the p1, p2, these are the partial pressure of the gases which are present here.
01:29
So therefore here this p total, it will be equal to partial pressure of the dry gas plus partial pressure of water vapor...
