Hello, so here the question is based on partial pressure.
00:06
Okay, so in order to calculate the partial pressure, we have the equation, partial pressure is equal to mole fraction multiplied by the total pressure.
00:28
Okay, so given in the question, we have the mass of nitrogen is equal to 5 .1 grams, then the mass of hydrogen is equal to 2 .83 grams and the mass of ammonia that is nh3 is equal to 5 .17 grams.
00:49
Okay, now what we need to find here is first for the mole fraction of nitrogen.
00:55
Okay, so we need to find the mole fraction of nitrogen.
01:00
Now mole fraction of nitrogen is equal to number of mole of nitrogen divided by the total moles.
01:10
Okay, then we need to find the number of moles for each and the total moles.
01:14
Okay, so number of moles of nitrogen is equal to mass divided by molar mass.
01:20
Now mass is 5 .1 and molar mass is 28.
01:24
Now this is equal to 0 .182 moles.
01:29
Okay, similarly, we can find for number of moles of hydrogen.
01:34
So that is equal to 2 .83 divided by 2.
01:39
Now that is equal to 1 .415 moles...
