How many moles of ammonium nitrate is created from 10.7 grams of ammonium nitrate? Thus how many grams of ammonium nitrate is needed to make exactly one mole of ammonium nitrate?

Answer 1

Ammonium Nitrate is NH4NO3

We need the get the molar mass of this. From the periodic table, the masses of each element in the chemical formula
N - 14
H - 1
O - 16
So for NH4NO3,
14 + 4*1 + 14 + 3*16 = 80 g/mol

To get the number of moles, we simply divide the given mass by its molar mass. Thus,
10.7 g / 80 g/mol = 0.13375 mol NH4NO3

Well if you have 1 mole of NH4NO3,
1 mol NH4NO3 * (80 g/mol) = 80 g NH4NO3
