Which formula for A-level chemistry do I use for this question?
Can anyone please explain how I can answer this question
A sample of Argon gas has a mass of 0.20g, at a pressure of 100 000 kPa and a temperature of 12C
Which volume does the gas occupy?
Should I be using the ideal gas law for this question?

Argon is 40 g/mol
0.20 g / 40 g/mol = 0.005 mol
V = nRT/P = (0.005)(8.314)(273.16+12) / (100) = _____ liters
Ideal gas law
PV = nRT
n = number of moles
R = gas constant = 0.08206 (atm∙L)/(mol∙K)
T = temperature in kelvins
P = absolute pressure in atm, kPa, bar, torr
V = volume in liters
