Mass of oxygen are formed is = 1.808 gm

Explanation:

Reaction equation of given condition

2N_2O = 2N_2 +O_2

No. of moles of N_2O

$N = \frac{m}{M}$

m = 5 gm & M = 44 gm

$N = \frac{5}{44}$

N = 0.113 mol

Now no. of moles of oxygen formed = $\frac{N}{2} = \frac{0.113}{2} = 0.0565$

Now mass of oxygen formed is

m = N M

m = 0.0565 × 32

m = 1.808 gm

Thus mass of oxygen are formed is = 1.808 gm
