Question

If I have 2.2 moles of gas at a pressure of 163.6 kPa and at a temperature of 37.9 0C, what is the volume of the container that the gas is in Liters?

Answer 1

1) List what you have and what you are looking for.

P = 163.6 kPa

V = ?

n = 2.2 mol

R = 8.314

T = 37.9°C / 311.05K (immediately convert to kelvin)

2) Rearrange your formula, input values, then calculate.

`PV = nRT\\ V=(nRT)/(P) \\ V=((2.2)(8.314)(311.05))/((163.6)) \\ V=34.77599841`

V = 35 L
