Question

The percentage of nitrogen in ammonium nitrate is 35.0%

• A. True
• B. False

Answer 1

The correct option is A True

• $$\begin{gathered} \mathrm{Molecular}\mathrm{formula}\mathrm{of}\mathrm{ammonium}\mathrm{nitrate}={\mathrm{NH}}_4{\mathrm{NO}}_3 \\ \mathrm{Molecular}\mathrm{mass}\mathrm{of}\mathrm{ammonium}\mathrm{nitrate}=28+48+4=80 \\ \mathrm{MAss}\mathrm{of}\mathrm{nitrogen}\mathrm{in}\mathrm{ammonium}\mathrm{nitrate}=28\mathrm{grams} \\ \%\mathrm{mass}\mathrm{of}\mathrm{nitrogen}=\frac{28}{80}\times 100=35\% \end{gathered}$$
• Hence the given statement is true.
