Two litre air formed 1915 ml of ozonised air when passed through Brodio's apparatus. The volume of ozone formed is:

Options

A. 85 ml
B. 170 ml
C. 225 ml
D. 42.5 ml

Answer

B

Explanation

There is a reduction of 1 volume.
When reduction in volume is 1, volume of `O_3` is 2.
volume of air `=2000ml`
Volume of ozonised air `=1915ml`
Reduction in volume `=2000-1915=85ml`
When reduction is 1 volume, volume of `O_3=2`
When reduction is 85 ml, volume of `O_3=85xx2`
`=170ml`
