Assuming ideal behavior, how much pressure will 2.75 mol hydrogen gas exert on the walls of a 4.00 l container at 35.0ºc?
a. 17.4 atm b. 19.8 atm c. 278 atm d. 296 atm

The correct answer is option A.

Explanation:

Pressure of the gas = P =?

Volume of the container in which gas is placed, V= 4.00 L

Temperature of the gas = T = 35°C = 308.15 k

Moles of gas = N = 2.75 mol

Using ideal gas equation:

PV=nRT

P = 17.3931 atm ≈ 17.4 atm

The pressure of the gas in the container is 17.4 atm.
