Answer : The mass of percent of nitrogen in the dyeing agent, picric acid is, 6.11 %
Solution : Given,
Molar mass of nitrogen = 14.01 g/mole
Molar mass of picric acid = 229.11 g/mole
As, we know that in [tex]C_6H_3N_3O_7[/tex], there are 6 carbon atoms, 3 hydrogen atoms, 3 nitrogen atoms and 7 oxygen atoms.
Formula used for the mass percent of nitrogen.
[tex]\text{Mass percent of nitrogen}=\frac{\text{Mass of nitrogen}}{\text{Molar mass of picric acid}}\times 100[/tex]
Now put all the given values in this formula, we get the mass of percent of nitrogen.
[tex]\text{Mass percent of nitrogen}=\frac{14.01}{229.11}\times 100=6.11\%[/tex]
Therefore, the mass of percent of nitrogen in the dyeing agent, picric acid is, 6.11 %
