Expert Answer:

Turpentine oil absorbs O3,

So, volume of ozone = volume absorbed by terpentine oil    = 10 mL

Hence, volume of O2     = 100 – 10 = 90 mL

 Mol. wt. of ozonised oxygen = WRT / PV

= (1.5 × 0.0821 × 273) / (1 × 1)

= 33.62

 Volume or mole ratio of O2 and O3 is 900: 100

Hence molecular weight of ozonised oxygen = (900 × 32 + 100 × a) / 1000

33.62 = (900 × 32 + 100 × a) / 1000

a = 48.2

Molecular weight of ozone = 48.2
