Answer 2

Answer:

The atoms number in 11.2 Liters of $SO_2$ = 9 × $10^{23}$ atoms.

Explanation:

There is 6.02 × $10^{23}$ molecules in one mole of $SO_2$ gas at STP.

Atomicity of $SO_2$ = 3

11.2 liter of $SO_2$ gas = 0.5 moles of $SO_2$

No of atoms in 1 mole of $SO_2$ = 3 × $N_a$

No of atoms in 0.5 mole of $SO_2$ = 3 × 0.5 × 6.03 × $10^{23}$

No of atoms in 0.5 mole of $SO_2$ = 9 × $10^{23}$ atoms approximately

Therefore, the number of atoms in 11.2 Liters of $SO_2$ = 9 × $10^{23}$ atoms.
