Type: MCQ-numerical-Hard-Class 12

If 0.1 mole of benzenediazonium chloride decomposes completely in a reaction involving the displacement of nitrogen, what volume of nitrogen gas is formed at standard temperature and pressure (STP)?

A

24 L

B

12 L

C

48 L

D

0.56 L

Correct Answer

Option A

Detailed Explanation

At STP, 1 mole of any gas occupies 22.4 L. Since 0.1 mole of benzenediazonium chloride produces 0.1 mole of nitrogen gas, the volume of nitrogen gas produced is 0.1 x 22.4 L = 2.24 L.
