I am looking for this answer too. Did you ever find it? I could really use the help

If mass remains the same while the volume of a substance increases, the
density of the substance will decrease. The increase in the volume is called expansion, while the decrease in the volume is called contraction.
</span><span>The density measures how much matter (mass) there is in a given amount of space (volume). So, if the mass stays the same and the volume increases then there is the same amount of mass ad before but in bigger volume so the density is decreased. </span>

Explanation:
The formula for ammonium nitrate is
NH4NO3
The trick here is to realize the 4 applies only to the hydrogen. The 3 applies only to the oxygen.
There are 2 nitrogens in the formula. So if the entire molecule represents 0.286 mols. The individual mols of each part of the formula is just multiplied by the number of moles of the molecule. In formula form
Number of moles of the atoms making up the molecule = number of atoms from the formula * mols of the molecule.
2*0.286 = 0.572 moles of Nitrogen
