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?
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

To determine the number of moles of ammonium nitrate created from 10.7 grams, you'll first need to calculate the molar mass of ammonium nitrate.
The molar mass of a compound is the sum of the atomic masses of each element in the compound. Ammonium nitrate (NH4NO3) contains the following elements:
- Nitrogen (N) with an atomic mass of 14.01 g/mol,
- Hydrogen (H) with an atomic mass of 1.01 g/mol,
- Oxygen (O) with an atomic mass of 16.00 g/mol.
Now, let's calculate the molar mass of ammonium nitrate:
(4 × molar mass of H) + molar mass of N + (3 × molar mass of O)
(4 × 1.01 g/mol) + 14.01 g/mol + (3 × 16.00 g/mol) =
4.04 g/mol + 14.01 g/mol + 48.00 g/mol =
66.05 g/mol
The molar mass of ammonium nitrate is approximately 66.05 g/mol.
To find the number of moles of ammonium nitrate created from 10.7 grams, divide the mass of the sample by the molar mass:
Number of moles = mass (in grams) / molar mass
Number of moles = 10.7 g / 66.05 g/mol
Calculate this:
Number of moles ≈ 0.162 mol
Therefore, approximately 0.162 moles of ammonium nitrate are created from 10.7 grams of ammonium nitrate.
Now, to determine how many grams of ammonium nitrate are needed to make exactly one mole of ammonium nitrate, you can reverse the calculation.
Number of grams = number of moles × molar mass
Number of grams = 1 mol × 66.05 g/mol
Calculate this:
Number of grams = 66.05 grams
Hence, approximately 66.05 grams of ammonium nitrate are needed to make precisely one mole of ammonium nitrate.
