Urea is a very important nitrogenous fertilizer. Its formula is CON2H4. Calculate the percentage of carbon in urea.
(C = 12, O = 16, N = 14 and H = 1)
Urea has the formula NH2CONH2 , i.e. CON2H4
Molecular mass of urea = 60 g/mol
Atomic mass of N = 14 & number of atoms = 2 i.e. 28 g/mol of urea
Thus the % = 2860 × 100 = 46.66 %
