Question

Answer 1

Answer #1

Solution :

The correct option is IV.

Calculation :

From the given reaction, it can be noted that 2 mol of NH3 produces 1 mol of N2.

Thus,

7.1 mol NH3 will produces = 7.1 mol x 1/2 = 3.55 mol N2

Since, 1 mol N2 = 6.023 x 10^23 molecule

Hence, 3.55 mol N2 = 3.55 x 6.023 x 10^23 molecules

= 2.14 x 10^24 molecule

= 2.1 x 10^24 molecule

Answer 2
