MCQ
The mass percentage of nitrogen in histamine is
- ✓$37.84$
- B$42.67$
- C$33.33$
- D$62.16$
✓
Answer
Correct option: A.
$37.84$
a
M.F. of Histamine is $\mathrm{C}_{5} \mathrm{H}_{9} \mathrm{N}_{3}$
M.F. of Histamine is $\mathrm{C}_{5} \mathrm{H}_{9} \mathrm{N}_{3}$
Molecular mass of Histamine is 111
Now, mass $\%$ of nitrogen $=\left(\frac{42}{111}\right) \times 100$
$=37.84 \%$
