More than twice the amount of nitrogen present in ammonium sulphate

Vedclass · Answer

(D) The molar mass of urea $(NH_2CONH_2)$ is $60 \ g/mol$. It contains $2$ nitrogen atoms,so the percentage of nitrogen is $(28/60) 	imes 100 \approx 46.67\%$. The molar mass of ammonium sulphate $(NH_4)_2SO_4$ is $132 \ g/mol$. It contains $2$ nitrogen atoms,so the percentage of nitrogen is $(28/132) 	imes 100 \approx 21.21\%$. Comparing the two,$46.67\% / 21.21\% \approx 2.2$. Therefore,urea contains more than twice the amount of nitrogen present in ammonium sulphate.

When equal weights of the two fertilizers,urea and ammonium sulphate are taken,urea contains
