Remarks:
Run 2

For Run 1, 6.9 g of sample was degassed for a 65 hour period. Starting pressure was 0.0009 mbar.

For Run 2, 10.4 g of sample was degassed for an 88 hour period. Starting pressure was 0.0009 mbar.

Conclusions:
Vapor pressure value determined using Static method was calculated as mean from Runs 1 and 2.
Vapour pressure was determined to be 3 Pa at 20 degrees Celsius.
