particle of a gas?

Question

An ideal gas is at a temp of 60 degree C and a pressure of 1.5 atm. What is the volume per particle of the gas??

please help, thanks

Answer 1

The volume for 1 mole would be

pV = nRT if n=1 p =1.5*101325=151987pa

V = RT/p = 8.31*(273+60)/151987 =0.0182m^3 = 18.2L

As one mole = 6.0210^23 particle , the mean volume for one particle is

0.0182/6.0210^23 = 310^-23m^3 by particle
