Urea

Vedclass · Answer

(A) To find the percentage of nitrogen,we calculate the mass percentage for each compound:$1$. Urea $(NH_2CONH_2)$: Molar mass = $60 \ g/mol$. Nitrogen mass = $28 \ g$. Percentage = $(28/60) 	imes 100 = 46.66 \%$.$2$. Ammonium sulphate $(NH_4)_2SO_4$: Molar mass = $132 \ g/mol$. Nitrogen mass = $28 \ g$. Percentage = $(28/132) 	imes 100 = 21.21 \%$.$3$. Ammonium nitrate $(NH_4NO_3)$: Molar mass = $80 \ g/mol$. Nitrogen mass = $28 \ g$. Percentage = $(28/80) 	imes 100 = 35 \%$.$4$. Calcium nitrate $Ca(NO_3)_2$: Molar mass = $164 \ g/mol$. Nitrogen mass = $28 \ g$. Percentage = $(28/164) 	imes 100 = 17.07 \%$.Thus,Urea has the highest percentage of nitrogen.
