3 moles of ammonium phosphate is how many grams?

There are 2 kinds of ammonium phosphate mono-basic NH4H2PO4 and di-basic (NH4)2HPO4.
The momobasic form:
14.01 + ( 6 x 1.01) + 30.97 + (4 x 16.00) = 115.04
115.04g/mol x 3 = 345.12g
The dibasic form:
(2 x 14.01) + (9 x 1.01) + 30.97 + (4 x 16.00) = 132.08
132.08g/mol x 3mol = 396.24

Well the chemical combination is NH4H2PO4
So 1 nitrogen, 6 hydrogen, 1 phosphorus, and 4 oxygen.
So for every mole of this substance there has to be 1 mole N, 6 moles H, 1 mole P, and 4 moles O.
So going by the period table, 1 mole would be:
14.01 + 6(1.008) + 30.97 + 4(16.00) = 114.728g
So 3 moles would be 3 times that or 344.184g
Now remember you are asking this question on the math and science question section. So all the bored mathematicians and scientists are looking for questions to answer. If you were to go post this under entertainment no one would be able to get it, lol

There are three ammonium phosphate exist, monobasic, dibasic, and tribasic. Some people said that NH3 is not strong enough to remove three protons from H3PO4, but there are plenty of indirect reactions to synthesis of
(NH4)3PO4. It is perfectly legitimate compound, albeit unstable (slowly decomposes to (NH4)2HPO4 and NH3). I bet your professor doubts that.

Calculate the molar mass of ammonium phosphate, (NH4)3PO4 molar mass = 3(14.01 g) + 12(1.01 g) + 30.97 g + 4(16.00 g) = 149.12 g/per mole
149.12x3=477.36 grams

(NH4)3PO4 (1 mole) Mol.mass
= (3x14) + (12x1) + 31 + (4x16)
= 42 + 12 + 31 + 64 = 149g/mole. = 149 x 3 = 447g.
(And, once again, Thumb's Downer, P**S off, the Mol.mass is correct, (1 mole) and that, times 3 moles = 447g...If you have a better answer, let's see it !!!)

1 mole = 131g
3 moles = 393g

Flying Dragon is the one out of 10 who did get it right.
Ammonia is not a strong enough base to remove the third H+ from phosphoric acid.

149.12g/mole X 3moles = 447.36 grams
