Answer:
Empirical formula : N₂H₈O₄S
Explanation:
Percentage of hydrogen = 6%
Percentage of nitrogen = 21%
Percentage of oxygen = 49 %
Percentage of sulfur = 24 %
Empirical formula = ?
Solution:
Number of gram atoms of H = 6 / 1.01 = 5.9
Number of gram atoms of O = 49 / 16 = 3.1
Number of gram atoms of N = 21 / 14 = 1.5
Number of gram atoms of S = 24 / 32 = 0.75
Atomic ratio:
N : H : O : S
1.5/0.75 : 5.9/0.75 : 3.1/0.75 : 0.75/0.75
2 : 8 : 4 : 1
N:H:O:S = 2 : 8 : 4: 1
Empirical formula : N₂H₈O₄S
