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
