Question

Dinitrogen monoxide gas decomposes to form nitrogen gas and oxygen gas. How many grams of oxygen are formed when 5.00 g of dinitrogen monoxide decomposes?

Answer 1

Mass of oxygen are formed is = 1.808 gm

Step-by-step explanation:

Reaction equation of given condition

`2N_2O = 2N_2 +O_2`

No. of moles of
`N_2O`

`N = (m)/(M)`

m = 5 gm & M = 44 gm

`N = (5)/(44)`

N = 0.113 mol

Now no. of moles of oxygen formed =
`(N)/(2) = (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
