What is the percent composition of each element in ammonium nitrate?
NH4NO3. Molar mass = 80
%N = (2*N/80)^100 = (2*14/80)*100 = 2800/80 = 35%?
The others are done the same way.
To find the percent composition of each element in ammonium nitrate, we need to know the chemical formula of ammonium nitrate, which is NH₄NO₃.
The percent composition of an element in a compound is determined by the atomic masses and the total molecular mass of the compound.
To calculate the percent composition, we need to follow these steps:
Step 1: Calculate the molar mass of ammonium nitrate.
The molar mass of a compound is the sum of the atomic masses of all the atoms present in the formula.
Molar Mass of NH₄NO₃ = (Molar Mass of N + Molar Mass of H) x 4 + Molar Mass of O x 3
Step 2: Calculate the molar mass of each element in ammonium nitrate.
The atomic masses can be found in the periodic table.
- Molar mass of N (nitrogen) = 14.01 g/mol
- Molar mass of H (hydrogen) = 1.01 g/mol
- Molar mass of O (oxygen) = 16.00 g/mol
Step 3: Calculate the percent composition of each element.
The percent composition is calculated by dividing the molar mass of the element by the molar mass of the compound and multiplying by 100.
Percent composition of N = (Molar mass of N / Molar mass of NH₄NO₃) x 100
Percent composition of H = (Molar mass of H / Molar mass of NH₄NO₃) x 100
Percent composition of O = (Molar mass of O / Molar mass of NH₄NO₃) x 100
By substituting the values in the above equations, you can calculate the percent composition of each element in ammonium nitrate.
