During diffusion substances move from the denser medium (meaning where there is more of the substance) to less dense medium (meaning where there is less of the substance).
Answer:
The value of partial pressure of oxygen
= 83.66 K pa
Explanation:
Volume of oxygen = 80 liters
Temperature = 50°c
The total pressure = 96 K pa
The partial pressure of water at 50°c is calculated from the tables.
= 12.344 K pa
The total pressure is given by

Put all the values in the above equation we get
96 = 12.344 + 
96 - 12.344
= 83.66 K pa
This is the value of partial pressure of oxygen.
