A 3 mol sample of gas is stored in a 5 L container at 2 atm and -10 C. If the container is heated to 50 C and 3 mols of gas are added, what is the pressure inside the container?

Answer 1

Since in a container the volume is a constant 5L. Simply apply ideal gas law to final conditions and solve for P.

P = nRT/V; P = (6)(0.0821)(50+ 273) / 5 = 31.8 atm
