If I contain 4 moles of gas in a container with a volume of 75 liters and at a temperature of 425 K, what is the pressure inside the container?

Answer 1

Again, you use the Ideal Gas Law: PV = nRT and solve for P, pressure

P = pressure = ?

V = volume in liters = 75

n = moles of gas = 4

R = gas constant = 0.0821 Latm/Kmol

T = temperature in Kelvin = 425K

Solving the Ideal Gas Law equation for P we have...

P = nRT/V

Plug in the above values and solve for P in atmospheres.
