A sample of ozonised oxygen diffuses `sqrt(2)` times faster than pure `SO_(3)` gas under identical conditions. The mass percent of `O_(3)` in the sample of ozonised oxygen is:

A certain volume of H_(2) effuses from an apparatus in one minute. The same volume of ozonised oxygen (O_(3)+O_(2)) mixture took 246 sec to effuse from appratus under identical conditions. Percentage of O_(2) by mole in mixture is:
