(C) The chemical formula of urea is $NH_2CONH_2$.The molar mass of urea is calculated as: $(2 	imes 14) + (4 	imes 1) + 12 + 16 = 60 \ g/mol$.The mass of nitrogen in one mole of urea is $2 	imes 14 = 28 \ g$.The percentage of nitrogen is calculated as: $\frac{	ext{Mass of Nitrogen}}{	ext{Molar mass of Urea}} 	imes 100 = \frac{28}{60} 	imes 100 \approx 46.67\%$.Rounding to the nearest whole number,the percentage is $46\%$.
