Since 1 mol NH3 contains 1 moles of N and 3 moles of the total number of moles of atoms in 0.25 moles of NH3 is:
Mole N = 1 X 0.25 = 0.25
Mole H = 3 X 0.25 = 0.75
_____
1.00
So the actual Answer is that it conatians only "ONE" mole.
Where there is one molecule of anys ubstance the total number of moles is calculated using this formula.
number of moles = mass of sample \ molar mass (g)

In one mole of NH3 there would be 1 mole of nitrogen and three moles of hydrogen, for a total of 4 moles.

to respond to your final question first, sure, "debris" genuinely contains atoms or molecules. the relationship you wrote, mol= #of debris/ avagadros #, is used for any concern the place you're going from moles to atoms or molecules, or vice versa. as an occasion, question B above. you ought to use molar mass basically while going from moles ----> mass mass ----> moles atoms ----> mass mass ----> atoms molecules ----> mass mass ----> molecules In different words, any time mass is in contact, as an occasion question C above. desire this allows a sprint.
