The weight of 1 L sample of ozonised oxygen at STP was found to be 1.5 g When 100 " mL of " this mixture at STP was treated with turpentine oil, the volume was reduced to 90 mL. Calculate the molecular weight of ozone.

Text Solution

Verified by Experts

Volume absorbed by turpentive oil`=10mL`
`=` volume of `O_(3)`
Volume of `O_(2)=100-10=90mL`
Mw of ozonised oxygen`=(WeightxxRT)/(PV)`
`=(1.5xx0.0821xxRT)/(1xx1)=33.62`
Volume of mol ratio of `O_(2)` and `O_(3)` `=900:100`
Mw of ozonised oxygen`=(900xx32+100xxa)/(1000)`
`33.62=(900xx32+100xxa)/(1000)`
or `a=48.2`
Mw of `O_(3)=48.2`
