`2 L` of 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. `425=.5 mL`

Answer

B

Explanation

`3O_(2) hArr 2O_(3)`
There is a reduction of 1 volume.
When reduction in volume = 1, then volume of `O_(3) = 2`.
Volume of air `= 2000 mL`
volume of ozonised air `= 1915 mL`
Reduction in volume `= 2000 - 1915 = 85 mL`
`:.` when reduction is 1 volume `implies` volume of `O_(3) = 2`
`:.` When reduction is `85 mL xx 2 implies 170 mL`
