Question

Suppose we have a 12.2L sample containing 0.50mol of oxygen gas, O2, at a pressure of 1atm and a temperature of 25oC. If all this O2 is converted to ozone, O3, at the same temperature and pressure, what will be the volume of the ozone?
3O2

Answer 1

$$3O_2 = 2O_3$$

$$V(O_2) : V(O_3) = 3:2$$

$$V(O_3) = {12.2L*2 \over 3} = 8.13L$$
