Question

Calculate the percentage of nitrogen and oxygen in ammonium nitrate.[Relative molecular mass of molecular nitrate is 80 ,H= 1,N =14, O= 16].

Answer 1

Step1: Write the given terms:

The molecular mass of NH₄ (NO₃) = 80g

H= 1, N =14, O= 16

Step 2: Find the percentage of oxygen:

Percentage of Oxygen:

As 80g of NH₄(NO₃) contains 48g of oxygen

Therefore, 100 g of NH₄(NO₃) contains = $\frac{48x100}{80}$=60%

Step 3: Find the percentage of nitrogen:

Percentage of Nitrogen:

As 80g of NH₄(NO₃) contains 28g of nitrogen

100 g of NH₄(NO₃) contains =$\frac{28x100}{80}$=35%

Step 4: Result:

Hence, the percentage of nitrogen and oxygen in ammonium nitrate is 35% and 60 % respectively.
