15% of oxygen is converted to ozone. The mass of ozone that can be prepared from 67.2 L of oxygen at N.T.P. will be

A

14.4 g

B

28.8 g

C

52.0 g

D

64 g

Text Solution

Verified by Experts

The correct Answer is:
A
`underset("3 vol")(3O_2) to underset("2vol")(2O_3)`
67.2 L of `O_2` produces ozone =` (2 xx 67.2)/(3) = 44.8 L`
sicne of efficiency is only 15%
`O_3` produced ` = (44.8 xx 15)/(100) = 6.72 L`
mass of `O_3` produced ` = (6.72 xx 48)/(22.4) = 14.4 g `
