Question Paper from: IIT JEE Mains Shift 2 25th July 2021

In Kjeldahl's method, 0.8g of organic compound is used. The percentage of Nitrogen came out to be 42%. The _____ ml of 1M H₂SO₄used to neutralize ammonia

Solution:

Chapter Name: Mole Concept

Difficulty Level: Moderate

$% N = \frac{1.4 N . V}{W}$

$42 = \frac{1.4 \times ( 1 \times 2 ) \times V}{0.8}$

$V = 12 m l$
