JEE Mains · Chemistry · STD 11 - 1. Some basic concept of chemistry
The mass percentage of nitrogen in histamine is
- A \(37.84\)
- B \(42.67\)
- C \(33.33\)
- D \(62.16\)
Answer & Solution
Correct Answer
(A) \(37.84\)
Step-by-step Solution
Detailed explanation
M.F. of Histamine is \(\mathrm{C}_{5} \mathrm{H}_{9} \mathrm{N}_{3}\) Molecular mass of Histamine is 111 Now, mass \(\%\) of nitrogen \(=\left(\frac{42}{111}\right) \times 100\) \(=37.84 \%\)
