Answer:
(a) 
(b) 
Explanation:
Hello,
In this case, since the both gases behave ideally, with the given information we can compute the moles of He in A:
Thus, since the final pressure is 3.60 bar, we can write:
The moles of helium could be computed via solver as:
Or algebraically:
In such a way, the volume of the compartment B is:
Finally, he mole fraction of He is:
Regards.

Answer:
0.05257 L/s
Explanation:
Step 1: Given data
The school uses 1200 gallons/day
Step 2: Convert "gal/day" to "L/day"
We will use the conversion factor 1 gal = 3.785 L.
1200 gal/day × (3.785L/gal) = 4542 L/day
Step 3: Convert "L/day" to "L/s"
We will use the following conversion factors:
4542 L/day × (1 day/24 h) × (1 h/3600 s) = 0.05257 L/s
Influencing Behavior is the only incorrect option. Everything else is correct including drawing conclusions.
