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.
