    Answer:

    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
