Final answer:
The relative formula mass of ammonium nitrate, NH₄NO₃, is 66.
Step-by-step explanation:
The relative formula mass of a compound is the sum of the relative atomic masses of all the atoms in its formula. To calculate the relative formula mass of ammonium nitrate (NH₄NO₃), we will use the given relative atomic masses: H (hydrogen) = 1, N (nitrogen) = 14, and O (oxygen) = 16.
The formula for ammonium nitrate isNH₄NO₃.
To find the relative formula mass, we need to add up the individual atomic masses of each element in the compound.
Relative atomic mass of hydrogen (H) = 1
Relative atomic mass of nitrogen (N) = 14
Relative atomic mass of oxygen (O) = 16
Now, we can calculate the relative formula mass of ammonium nitrate:
NH₄NO₃ = (1 4) + 14 + (16 3) = 4 + 14 + 48 = 66
Relative formula mass of ammonium nitrate = 66
