We have this data from the problem and let's find first of all the average molecular weight of the feed steam.
00:17
For this purpose we will need the molecular weight of the hydrogen gas.
00:27
It is 2 .0 gram per mole and molecular weight.
00:37
Of the nitrogen gas, it's 28 .0 gram per mole.
00:48
And the average molecular weight of the feed will be 28 .0 times 0 .25.
01:08
This means persons, plus 2 .0 times 0 .25.
01:10
This means persons, plus 2 .0 times 0 .775.
01:23
This equal to 8 .5 gram per mole.
01:34
The next let's convert the rate of feed from the kilogram per hour to the mole per hour.
01:48
So rate of feet equals three thousands times 10 in power 3, conversion into the gram, divided to 8 .5 gram per mole.
02:15
And as a result, we have 352 .94 times 10 to 3 .3 mole per hour...
