The fraction of gas phase molecules is calculated by the division of final pressure to the initial pressure.
Fraction = 
(1)
Here, initial pressure = 1.0 atm
final pressure = 
First, convert torr into atm
1 atm = 760 torr
final pressure = 
= 
Now, put the value of initial and final pressure in formula (1)
Fraction = 
= 
Thus, fraction of the gas phase molecules =

Explanation:
The correct answer is Ozone.
Ozone, sometimes known as O3, is a poisonous and unstable gas. Ozone is a potent allotrope of oxygen; it absorbs heat when it is present in large quantities all over the earth. A molecule called ozone has three oxygen atoms in it. At ground level, it is dangerous and unstable. O3 O3's efficacy in treating infections, wounds, and several disorders has been extensively established. Before the turn of the century, it was employed to sterilize drinking water. One study found that ozone could cure 114 different ailments. Headaches, coughing, a dry throat, difficulty breathing, a heavy feeling in the chest, and fluid in the lungs can all be side effects of ozone exposure.
