1.	Six hundred millitres of ozonised oxygen STP was found to weigh 1 gm. What is the volume of ozone in the ozonised oxygen?A. 200 mlB. 150 mlC. 100 mlD. 50 ml
Answer» Correct Answer - A Let the volume of `O_3` be `x` ml Volume of `O_2` present `=(600-x)ml` 22400ml of `O_3` and `O_2` at STP will weigh 48 and 32 gm respectively. The weight of `xml` of `O_3=(x xx48)/(22400)gm` The weight of `(600-x)ml` of `O_2=((600-x))/(22400)xx32` Total weight of ozonised `O_2(600ml)` is `(48x)/(22400)+((600-x)xx32)/(22400)=1.0` `x=200ml`
