Question

A sign make is given 1.33 moles of neon gas in a 0.500 liter container at a temperature of 299K. What is the pressure of the container

Answer 1

You need the IDEAL GAS LAW - PV = nRT

P = pressure = your unknown

V = volume

n = mol

R = 8.314

T = temperature

Rearrange the equation to have P alone on the left side of the equation:

P = nRT

V

Answer 2

Assuming ideal gas:

PV = nRT Solving for P:

P = nRT/V = (1.33 mol)*(0.0821 atm.L/(mol.K))*299K/0.500L

P = 65.297414 atm

Rounding to 3 significant figures:

P = 65.3 atm
