Question

At 1800 K, oxygen dissociates into gaseous atoms:

O2(g) ⇌ 2O(g)

K for the system is 1.7 × 10–8. If 2.2 mol of oxygen molecules is placed in a 5.5 L flask and heated to 1800 K, what percentage by mass of the oxygen dissociates? How many O atoms are in the flask?

Relerence
At 1800 K, oxygen dissociates into gaseous atoms:
O2(8) = 20(g)
K for the system is 1.7 x 10-8. If 2.2 mol of oxygen molecules is placed in a 5.5 L flask and heated to 1800 K, what percentage by mass of the oxygen dissociates? How many O atoms are in the
flask?
