n/v = p/rt

n/v = 4.04x10^-13 / (8.31x297) = 1.66x10^-16 mol/m³

1.66x10^-16 mol/m³ * (1/100cm)³ = 1.66x10^-22 mol/cm³

but something is wrong, please verify and she what i am doing wrong

And you have 1.66x106.22x10^23

Actually now that I see it, you are finding per cm

R has the units J/mol.K

J = 1 Pa m

i only got 1 more try at answering this question :(

(1.66x10^-16 mol/m³) * (m/100cm)³ * (6.022x10^23/mol) = 99.97 molecules/cm³

am i correct now?
