. The normal boiling point for oxygen is at 800 torr and – 193°C, the most likely state of a sample of pure oxygen is

Gaseous at standard conditions.

Explanation:

Hello,

In this case, for the given normal boiling point of oxygen, we can notice those are conditions far away from the standard conditions which are 25 °C. In such a way, since the standard temperature is by far higher than the normal boiling point, the most likely state of a sample of pure oxygen would be gaseous since the molecules will move based on the kinetic theory of gases due to the  relatively high temperature which make them be separated and moving all around.

Best regards.
