Explanation:
Molar mass of N2H4CO = 60 g/mol
Given that the relative atomic mass mass of each element is known, We discover that;
Percentage by mass of nitrogen = 28/60 * 100 = 46 .7%
percentage by mass of hydrogen = 4/60 * 100 = 6 67%
Percentage by mass of carbon = 12/60 * 100 = 20%
Percentage by mass of oxygen = 16/60 * 26.67%
