The vapour pressure was calculated using a semi logarithmic linear regression based on the Antoine equation (with 95 % confidence interval).

Conclusions:
The vapour pressure of Adrost-4-ene-3, 17-dione is 0.00000098 Pa at 20°C.
Executive summary:

The vapour pressure of the substance of 9.8*10-7 Pa at 20°C was calculated using a semi logarithmic linear regression based on the Antoine equation (with 95% confidence interval). The temperature dependence of the vapour pressure was determined with the Knudsen effusion method using a vapour pressure balance in the temperature range of 75 -110 °C.
