Question
Plants need nitrogen to grow, so many fertilizers consist of nitrogen-containing compounds.
Calculate the mass percent composition of nitrogen in NH3 .
Express your answer using four significant figures
Calculate the mass percent composition of nitrogen in CO(NH2)2 .
Express your answer using four significant figures.
Calculate the mass percent composition of nitrogen in NH4NO3 .
Express your answer using four significant figures.
Calculate the mass percent composition of nitrogen in (NH4)2SO4 .
Express your answer using four significant figures.
Explanation / Answer
mass percentage of N in NH3 = 14*100/17 = 82.35%
The mass percent composition of nitrogen in CO(NH2)2 = 2*14*100/60 = 46.67%
The mass percent composition of nitrogen in NH4NO3 = 2*14*100/80 = 35.00%
The mass percent composition of nitrogen in (NH4)2SO4 = 2*14*100/132 = 21.21%
