Answer: The total pressure inside the container is 1.07 atm
Step-by-step explanation:
To calculate the total pressure of the container, we use the equation given by Raoult's law, which is:

where,
= partial pressure of nitrogen = 0.800 atm
= total pressure
= mole fraction of nitrogen = 0.750
Putting values in above equation, we get:

Hence, the total pressure inside the container is 1.07 atm
