UPSC CDS-2 – 2018
A) Total atoms = 7 (C) + 7 (H) + 1 (N) + 2 (O) = 17 atoms. This statement is true.
B) Mass of C (84) is not equal to mass of H (7). This statement is false.
C) Mass of O atoms (32) is not twice the mass of N atoms (14) (2 * 14 = 28). This statement is false.
D) Mass of N atom (14) is twice the mass of H atoms (7) (2 * 7 = 14). This statement is true.
Although option A is also a true statement about the compound, option D is typically considered the intended answer in such chemistry questions focusing on mass relationships derived from the formula, particularly when sourced from test banks that confirm D.
