Answer:
You will need to use the Ideal Gas Law to solve this problem:
P
V
=
n
R
T
Explanation:
To find pressure
(
P
)
, derive from the Ideal Gas Law:
P
=
n
R
T
V
Gather up your known values, and plug them into the equation.
There are a few points to make here, Temperature
(
T
)
must be converted to Kelvin.
R
= Ideal Gas Constant. This can have many forms. The one I used below is the one that I am most familiar with. Be aware of this though, and check which value you should be using per your curriculum.
n
=
91.5
m

V
=
69.5
L
T
=

Finally,
P
=
