Applicant's summary and conclusion

Conclusions:
Vapour pressure of 4-nitro-o-xylene is 21.73 Pa at 25 deg C.
Executive summary:

The vapour pressure of a substance is defined as the saturation pressure above a solid or liquid substance. It is a measure of the tendency of a material to vapourise. The higher the vapour pressure the greater the potential.

Thus, in this case vapour pressure of 4-nitro-o-xylene is 21.73 Pa at 25 deg C.
