A particular question we have been asked that with what mass of nitrogen would one gram of hydrogen combine to form nh3, that is ammonia, all right? so, nh3 is basically our molecule here.
00:12
And here we have two elements that make up this molecule.
00:15
One is nitrogen, whose mass is 14 grams.
00:18
This is the molar mass, all right? its atomic mass is 14 atomic units.
00:22
That's why its molar mass is 14 grams.
00:25
That's one for one nitrogen molecule, all right? sorry, one nitrogen atom.
00:31
And now for hydrogen, we have the molar mass as 1 gram.
00:37
Now by this formula, we can easily know that one mole of nitrogen reacts with 3 moles of hydrogen, right? because in this formula we have 1 and 3h...
