    The percentage of nitrogen in urea is about:
    The percentage of nitrogen in urea (CH4N2O) is 46.6%. To calculate the percentage of nitrogen in urea, we can use the following formula: (mass of nitrogen / mass of urea) * 100% The mass of nitrogen in urea is 28 g/mol, and the mass of urea is 60 g/mol. Therefore, the percentage of nitrogen in urea is: (28 g/mol / 60 g/mol) * 100% = 46.6%
