2.04 atm

Explanation:

The pressure of the gas can be found by using the equation of state for an ideal gas:

where

p is the gas pressure

V is the gas volume

n is the number of moles

R is the gas constant

T is the absolute temperature of the gas

For this gas we have:

n = 0.316 mol (moles)

V = 4.00 L (volume)

T = 315 K (absolute temperature)

(gas constant)

Therefore, the gas pressure is
