Chemistry Question 12

Question

Using the Ideal Gas Law and the given measurements, solve for the unknown variable.

V: 55.213 L

n: 4.5344 mol

T: 214.27 K

P: ?

Answer 1

The general Ideal Gas Law formula is

PV = nRT

For this scenario you want to solve for the Pressure (P) and then plug in the values that you know from the information given in the question

P = nRT / V

P = (4.5344 mol x 0.08206 L*atm / mol K * 214.27 K) / 55.213 L = 1.444

meaning that the pressure of the gas in the container is 1.4440 atm
