need help with this physics ideal gases question!!

Issac physics G2.1

What is the volume of a mole of gas at atmospheric pressure (1.01*10^5 Pa) and at 20 ∘C? Give your answer to two significant figures.

Just use the ideal gas equation and rearrange for volume?
Reply 2
Use pV=nRT, rearrange for V

pV = nRT
V = (nRT)/p
V = [1 x 8.31 x (20 + 273)] / 1.01*10^5
V = 0.0241 m^3 or 24107 cm^3
To 2 s.f = 0.0240 m^3 or 24000 cm^3
Hope this helps!
