The correct answer is 14
Mass of organic compound = 0.2 g
Volume of \(N_2\) gas evolved at STP = 22.4 mL
Mass of \(N_2\) gas evolved
\(= \frac{22.4 × 10^{−3} × 28}{22.4} \)
= 0.028 g
Percentage of nitrogen in the compound :
\(=\frac{0.028×100}{0.2}\)
=14%
Given below are two statements I and II.
Statement I: Dumas method is used for estimation of "Nitrogen" in an organic compound.
Statement II: Dumas method involves the formation of ammonium sulfate by heating the organic compound with concentrated H\(_2\)SO\(_4\). In the light of the above statements, choose the correct answer from the options given below:
While estimating the nitrogen present in an organic compound by Kjeldahl’s method, the ammonia evolved from 0.25 g of the compound neutralized 2.5 mL of 2 M H2SO4. The percentage of nitrogen present in organic compound is ________
Let \( y = f(x) \) be the solution of the differential equation
\[ \frac{dy}{dx} + 3y \tan^2 x + 3y = \sec^2 x \]
such that \( f(0) = \frac{e^3}{3} + 1 \), then \( f\left( \frac{\pi}{4} \right) \) is equal to:
Find the IUPAC name of the compound.
If \( \lim_{x \to 0} \left( \frac{\tan x}{x} \right)^{\frac{1}{x^2}} = p \), then \( 96 \ln p \) is: 32
